GRP fibreglass tank covers, pit covers & hoist covers

Is your tank roof letting you down?

Your tank roof cover faces a double threat. Not only is steel prone to corrosion and (in time) failure, but condensation and fumes inside your tank can speed up this process.

A corroding tank roof not only risks contaminating your tank's contents, but can weaken the structure – quickly becoming a health and safety issue.

GRP fibreglass roof covers

You can avoid this, and expensive replacements, with a GRP fibreglass roof. You'll no longer have to worry about corrosion, structural instability or weathering – for many years.

We can mould fibreglass into almost any shape and customise it for almost any chemical conditions – making it the ideal material for your tank roof.

Manufactured and installed by us

Sui Generis can both manufacture and install a custom fibreglass covering, built specifically for your needs – helping you save money long term.

One of our structural engineers will create a design to your specifications, allowing for weather conditions such as wind and snow loadings. Then the appropriate resins and additives for the chemical environment will be selected, and we'll mould and assemble your new tank roof.

Best of all, we can assemble it on-site and fit it to your tank with a minimum of disruption and downtime, ensuring you get full use of your tank back fast.

GRP Fibreglass roof & cover guide

Tank roofs and covers protect the contents of your tanks or bunds and help ensure their structural integrity. But steel tank lids will corrode and fail over time due to harsh weather conditions, rust and chemical attack.

This can leave your tanks and their contents vulnerable and pose a health and safety risk to your staff – often resulting in expensive replacements.

However, if you replace your tank roof or cover with a new fibreglass roof from Sui Generis, you can protect the contents of your tank and avoid the problems associated with steel – indefinitely.

Why use a fibreglass roof?
