Aluminium Access Covers: The Ultimate Guide

There are many aluminum access cover designs in the market. However, choosing suitable aluminum access covers depends on in-depth understanding of features, design, material grade and specifications.

This guide has all information about aluminum access covers – let’s dive right in.

What Are Aluminum Access Covers?

An access cover is a removable lid that is placed over any man-made opening for the purpose of restricting access. Access covers can be made from materials like aluminum or stainless steel or composite materials.

Therefore, aluminum access covers are those that are made from aluminum material. Most aluminum access covers are either rectangular or square in shape and are hinged or connected to a lifting mechanism.

Aluminum Access Covers Vs. Stainless Steel Access Covers

Aluminum Access Covers

Aluminum Access Covers

These are access covers made from aluminum material. Aluminum access covers are non-magnetic with low density and good conductivity properties. These access covers are lightweight with high ductility properties.

Aluminum access covers are usually used in industries such as transportation, electrical and households. Aluminum access covers can work better in cold temperatures because when it gets cold, the material becomes even stronger.

Stainless-steel Access Covers

These are access covers made from stainless-steel material.

Stainless steel access covers are usually magnetic, with high tensile strength and can be made with any of the stainless-steel grades. They can resist heat and are very durable with low maintenance requirements.

They are also resistant to corrosion and can be used for both indoor and outdoor applications. Access covers made from stainless-steel can be used in industries such as automotive, architecture and for household applications.

Benefits Of Aluminum Access Covers

Aluminum access covers are light weight under 16kg and are easy to handle and also ensures safety. They are cost effective since they are durable and can offer their services for a very long period of time.

Apart from safety, aluminum material is heat resistant and can protect the enclosed components from damage by heat. Aluminum access covers are corrosion resistant and can ensure the safety of the enclosed applications.

They are made of a rubber seal for preventing odor.

Besides, they are also designed with a recessed lockbox which is also very easy to handle.

Some aluminum access covers are coated with an anti-slip coating.

Another benefit is the aesthetic appearance where the access cover matches the appearance of the surrounding space finishing.

They are also designed with fall through prevention gates for safety reasons.

Aluminum access covers help save on space by enclosing components and offering a covering for them leaving space for other purposes.

They also offer ease of accessibility through keyed lifting slot and recessed lifting handle.

Grating design enables personnel the ease of maintenance and cleaning without the risk of falling.

Choosing Material Grade For Aluminum Access Covers

When choosing an aluminum grade for making access covers consider the following factors;

Corrosion Resistance

Aluminum alloys with excellent corrosion resistance are 6061, 5052 and 1100 alloys.


Alloys such as 7075, 2024 and 2011 have high strength while others like 1100 and 3003 have medium strength.


Any aluminum alloy which is resistant to corrosion and strong can offer durability.

End-use Applications

The end use application is also an important factor to consider since not all grades of aluminum can serve the same purpose.


The grades of aluminum that have excellent formability properties include alloy 1100 and alloy 3003



Alloy 2011, 6061 and 3003 can be easily machined while others are hard to machine.


There are two grades of aluminum with excellent weldability including alloy 1100 and allow 3003.

How To Choose Aluminum Access Covers

Aluminum Access Covers Should Have A Fall Prevention Grating

The safety grating panels are fixed underneath the access covers to eliminate the risk of falling when working around the manholes. Engineered grating system is meant to prevent falls during cleaning and maintenance.

The grating system should be made of marine grade aluminum since this is of good quality.

They Should Be Designed With Recessed Lock System

Recessed Lock System

The recessed lock system also made with aluminum is fixed beneath the access cover for purposes of offering a safe and secure lock system. A lock box designed is generally meant to offer security to the aluminum access cover and the grating system beneath and the components.

This choice will depend on the application of the access cover, for instance, when working in pumping stations, overflow chambers etc.

Consider A Spring Assist When Choosing An Aluminum Access Covers

The spring assist is usually necessary when handling heavy aluminum access covers and safety grating. Spring assist is a special consideration for aluminum access covers when handling applications such as flowmeter pits, valve pits, overflow chambers etc.

Consider Locking Mechanism Of 900 Access Cover

This enables the covers to fully opened and can be held at an upright position during cleaning and maintenance for the manhole applications. Consider this feature especially when dealing in valve pits, water pumping stations, overflow chambers etc.

An Aluminum Access Cover Should Have A Slab Skirting

This is usually meant for forming a concrete opening under the access cover frame to offer protection from any element that can cause harm. This choice will depend on the application of the access cover, for instance, when working in pumping stations, overflow chambers etc.

Consider Aluminum Access Covers That Have Penetrations

These are access points meant to offer safer operations that can access valves and other instruments at the ground level even if you don’t lift the cover. Consider this feature especially when dealing in valve pits, water pumping stations, overflow chambers etc.
