Materials To Choose For Safety Signs

Safety signs are made from different sheet metal materials. Here we’ll focus on various sheet metals which include:

Alloy Steel Sheet Metal

This is a type of steel metal that has undergone alloying with manganese, chromium, vanadium, nickel, and tungsten to improve its mechanical properties.


  • It is less fragile
  • Has superior strength and hardness
  • Corrosion and heat resistant
  • Tough and weldable


  • The more the alloying elements added the higher the price
  • It can be difficult to machine resulting to a poor surface finish

Aluminum Sheet Metal


  • Its soft, lightweight, ductile and malleable
  • Corrosion-resistant
  • It’s easy to work with machining and welding
  • Good thermal and electrical conductor
  • Recyclable


  • It’s not that strong
  • It’s more expensive than steel

Stainless Steel Sheet Metal

It is originally known as ‘rustless steel’.


  • It’s highly resistant to oxidation and hence maintains its condition for years.
  • It’s strong and durable
  • It has a high melting point making it ideal for industrial and construction-related fields


  • it’s not cost-effective
  • it gets dirty easily
  • The high melting point makes it difficult to use in welding

Carbon Steel Sheet Metal

It’s an alloy metal consisting of carbon and iron.


  • It’s easily mouldable
  • It’s very strong


  • Its strength makes it difficult to work with
  • It’s prone to rust and corrosion

Tool Steel Sheet Metal

Like alloy steel, it has various components in different percentages.


  • Resistance to abrasion
  • Works well in high temperature
  • Tough and rigid
  • High surface finish


  • Not ideal for wet environments

Galvanized Steel Sheet Metal


  • Affordable
  • Easy to clean and maintain
  • Durable
  • Corrosion-resistant


  • Large scale galvanization is expensive
  • It’s resistant to red rust but can develop white rust if exposed to wet areas

Every type of sheet metal has its pros and cons. Choose one according to the functionality of your safety sign.

That is, if you want to place your sign outdoors, choose one that can withstand the various weather conditions.

Where Use Safety Signs

Safety signs are used in the following places:

  • Construction sites- site safety
  • Parking- don’t park here
  • Supermarket- wet floor
  • Office- staff only
  • Factory- restricted area
  • Restraint- don’t spit here
  • swimming pool – deep end
  • Farms- no way through
Importance Of Safety Signs

All businesses understand the importance of safety signs but not all of them proactively consider installing them. Here are the benefits of safety signs:

i. Legal requirement– They are a legal requirement and installing them in your business demonstrates regulatory compliance.

They mandate signs to be clear, legible, visibly placed, and well-maintained.

ii. Guarding employees and the public at large

Occupational safety hazards could pose risks not only to employees but also to members of the public.

Unlike employees who have gone through training and know what to do in case an accident occurs, other people don’t.

Safety signs educate members about falling objects for example and encourage them to avoid such an area.

They also provide contact details in case of danger. Remember hurting a civilian could ruin your reputation as a business. Better be safe than sorry.

iii. Better safety benefits everyone

Many people get injured at their workplace resulting to decreased morale and productivity.

Safety signs are one of the most visible and important to a healthy work environment and workplaces.

With more safety can foster better mutual relationships and loyalty with their customers

iv. States safe methods of work and hazards

Safety signs not only remind workers of effective ways of working but also highlights the safest exit routes, location of first aid kits, or manage fire risks.

Some organizations have designed their own safety sign that is multi-purpose.

They contain the company’s information and crucial safety policies and are storage for first aid kit.

v. Immediate visual communication safety messages

The primary goal of a safety sign is to communicate the most important safety message in the most simples way possible.

A well-designed and well-positioned sign with a clear pictographic illustration does exactly that.

How To Fabricate Safety Signs

The process includes:

i. Design– you can pick the design on the website and add some details like the logo and the name of the company or design your own from the scratch and email it to us.

ii. Cutting– we cut sheet metals to achieve the desired look. We select cutting tools according to the strength and thickness of the metal. Tools include mills, blades, laser cutters, waterjets, etc

iii. Forming-it includes the following processes:

  • Bending– we use press Blakes to fold sheet metals to the desired shape. Understanding the material properties is crucial, especially for extremely complex bends.
  • Punching-sheet metal is placed between hollow shapes die and punch, pressure is applied to create the desired shape
  • Extrusion– is similar to punching only that the punched materials are released downwards instead of getting rid
  • Embossing– is used to create a raised or recessed shape, texture, or pattern the metal sheet

iv. Finishing– the above processes cause rough edges on the sheet metal. We polish the edges and paint or coat them to protect them from heat and UV rays

v. Assembly– this is the final process. We assemble the sheet metals according to the design of your safety sign. Processes like welding, bolting or attaching are used to assemble the end product.

vi. Printing– here we add all necessary information on the safety signs either by etching, dot peening, flexographic printing, etc.

Types Of Safety Signs

There are four main categories of safety signs which include:

Mandatory Signs- MUST DO

Stipulate actions that must be taken to adhere to statutory requirements. ie ‘wear safety boots’ sign in a construction site.

Mandatory signs are rectangles in shape to accommodate the number of texts needed.

The text or pictograms are centrally located.

Mandatory signs

Mandatory signs

Emergency Signs- SAFETY FIRST

These signs offer information such as emergency exits, escape routes, or rescue facilities in case an accident occurs.

They are green in color, rectangle or square in shape with imagery or text written in white positioned at the center.

Emergency sign

Emergency signs

Prohibition Signs- CAN’T DO

These are command signs that contain ‘DO NOT’. They are used in a workplace to fortify instructions that ban dangerous activities.

These signs are round in shape with a white background.

That is, indicating the command in black and a single diagonal cross descending from left to right at an angle of 45 degrees.

prohoibition sign

Prohibition sign

Warning Signs-HURT YOU

These signs warn of danger or hazard. They inform people of a nearby danger ie restricted area or falling hazard sign.

They come in an equilateral triangle shape with a yellow background and a black text indicating the hazard at the center.

Warning signs

Warning signs

Danger Sign-KILL YOU

They warn the public about potentially life-threatening hazards or hazardous conditions.

The header is oval inside a rectangular background. The word danger in bold capital letter to alert people

Danger sign

These signs have a red background and white text. The red color makes it easy for anyone to spot fire fighting equipment in case of a fire outbreak.

They indicate the location of fire extinguishers, fire horses, fire blankets, etc.

OSH Signage Requirements For Safety

Occupational Safety and Health Administration (OSHA) standards keep changing to set and enforce standards. OSHA has adopted American National Standards Institute (ANSI) Z35.1-1968 standard severally.

First in 1971, to state the danger signs, exits signs, directional signs, caution signs, radiation warning signs, safety instruction signs, and informational signs.

The adopted format entails a safety header or a word such as “danger” to control the risk level of hazard and a simple condensed text.

The second time OSHA adopted the updated ANSI Z535-2011(R2017) standard was in 2017. It is clearer than the first one as it highlights hazards and policies.

These refurbished structure include a safety header like “danger” a text legend, and symbols or pictograms. The layout applies to signs, labels, and tags.

It’s worth noting that not all OSHA standards comply with ANSI Z535-2011; some are specific.

Also, even though OSHA has adopted updated sign layouts as part of its standards, both sign structures continue to be biddable with OSHA accident prevention signage standards.

I know you are confused about whether to get OSHA or ANSI.

Don’t be because they have the same goal; to inform workers of the potential hazards and policies in their workplace.

ISO Requirements For Safety Signs

The ISO standards have recently been updated to incorporate the new safety signs globally. These standards have been put in place to ensure everyone speaks the same language when it comes to safety.

They include:

ISO 7010–   dictates safety signs associated with accident prevention, fire protection, health hazard information, and emergency evacuation.

Such as restricted areas on construction sites and emergency exits.

ISO 7010 was developed by ISO subcommittee  ISO/TC 145/SC 2, Safety identification, signs, shapes, symbols, and colors.

ISO3864-1– features the color and shape of the sign

ISO- 3864-3– references the design style and the design principle

Best Surface Finish For Safety Signs

Sheet metals are strong however adding a surface finish improves their performance and durability. Here are finishes you can add to your metal:

i.Metal plating– here metals are accumulated on the substrate to form a thin protective layer over the substrate. Two methods can be used electroplating or an electroless plating process.

It provides the following benefits to the safety sign

  • Reduces possibility of corrosion
  • Provides aesthetic decoration
  • Enhances solderability
  • Increases strength
  • Decreases friction
  • Changes conductivity
  • Increases paint adhesion
  • Improves magnetism

ii. Buff polishing– This technique creates a smooth surface by use of a cloth wheel to buff the product surface. It gives the sign a smooth, shiny effect

iii.Powder Coating is a dry coating process used on sheet metal. A dry powder is put in through an electrostatic process, then cured with heat.

It provides the following benefits to the safety sign:

  • High-quality finish that is aesthetically pleasing and functional
  • Durable finish
  • Produces a textured or glossy look on the safety sign

iv. Sand Blasting is a technique used to prepare a surface before painting. Fine particles are propelled at high velocity to clean the surface. It results in a smooth texture

Other sheet metal finishes include:

  • Shearing
  • Sawing
  • Punching
  • Laser cutting
  • Forming
  • Welding
  • Spot welding
Factors Determining Safety Signs Prices

They include:

  • Size- the bigger the size the more content is required hence higher prices
  • The finished look- different finish looks have different prices
  • Different shops price their goods differently. Equally, if you buy your safety signs online you will have to pay a shipping or delivery fee that increases the end price of the goods.
  • Custom made shorts are unique but more expensive than the normal signs
  • Safety signs are made from different materials that differ in density and texture hence they affect the price
  • Seasons- during offpeak and sales seasons you will pay less for safety signs
ANSI Safety Sign Standards

American National Standards Institute (ANSI) is an independent organization that authorizes numerous industries.

ANSI safety sign formats are based on the ANSI Z535-2011 standard which has 3 relevant elements which include; a safety header, images, and a sign legend.

They include:

i. They must be readable and strategically placed so as not to cause distraction or create hazards themselves. Must have a safe viewing from a distance.

ii. They must not be placed on or opposite moveable objects like doors, windows, etc.

iii. Signs must be displayed with illumination or retro-reflectiveness as required for sufficient clarity.

iv. Where lighting is insufficient or colors are not clear a subsidiary illumination must be used.

v. Where illumination may be interrupted, a retro-reflective material or emergency lighting can be used

vi. Safety and fire equipment signs must be visible near the equipment.

vii. Safety signs must be shielded from environmental damage such as fading or any other caused by the weather conditions.

Choosing Font For Safety Signs

The font you choose for your safety sign can make or break your design meaning it will not meet its purpose. Use easy-to-read fonts like Verdana, Perpetua, and Times new roman that are easy to read from a distance.

Avoid any italics font or calligraphed fonts as they are not clear. Shy away from using upper case text on your safety sign.

All caps letters seem to slow down the reader’s comprehension. Only use all caps as the header like (HIGH VOLTAGE) title case for action statement like (Risk of Electrocution  ) and a sentence for hazard statement( Authorised person only).

Safety Signage Mounting Options

Safety signs are mounted according to where they will be positioned whether on the wall, floor, or outside. Here are mounting options that we have, they include;

i. Wall mount signs– are single-sided lightboxes that hang on a solid surface. It has Internal corner clips, U-angle channel straps, and external and 90-degree angle mounting clips.

ii. Saddle Mount Signs can be used for single or double poles. Saddle brackets are welded to the top and bottom of the sign cabinet.

iii. Center Pole Sign Mounting -The center pole sits in the saddles on top and bottom.

iv. Thru Pole Sign Mounting-the pole goes through the cabinet. The sign cabinet slides over the pole and attaches to the saddle mounting brackets on the top and bottom.

v. Match Plate Sign Mounting– it is common for existing poles with single or double poles.

vi. Mounting Signs Between Two Poles-the sign is mounted between the two posts and welded or bolted into place.

vii. Cantilever Sign Mounting-this technique is not common. The cabinet attaches directly to the posts, hangs from the posts, or attaches with brackets.

Recommended Safety Sign Sizes

Safety signs come in the following shapes:

i. Discs for prohibitions and instructions

ii. ΔTriangles for warnings

iii. □Squares and rectangles for emergency and information signs

A safety sign should not be too big to overwhelm the space equally it should not be too small that people strain to view.

It should be large enough to be clearly read and seen by everyone irrespective of their height or size.

While positioning your signs consider the environment, lighting, and viewing distance to comply with Australian Standard AS 1319. This is the perfect way to determine the size of your sign.

Here is a minimum size for a pictogram and worded sign for the work environment:

  • Pictogram size is to be at a minimum of 15mm per meter of viewing distance
  • Text size- readable
  • Upper case: 5mm per meter of viewing distance
  • Lower case: 4mm per meter of viewing distance

Below is an image showing the size and position of a sign

Color Options For Safety Signage

Signs come in different colors. However, this is not the best place to state your favorite color as every color has a meaning.

Note if you breach these Health and Safety regulations you will have committed a criminal offense that can result to serious fines or even imprisonment.

Here are the colors that are used on signs, their meaning, and the instruction they are meant to put across:

i. Red– Represents the prohibition sign which means dangerous behavior; stop, shutdown, evacuate

ii. Yellow / Amber –it represents a warning sign which means Be careful, take precautions

iii. Blue- Mandatory sign specific behavior or action or wear of protective equipment

iv. Green-Emergency escape/ First-aid sign doors exit, escape routes, equipment, and facilities
