The attic ladder is counterbalanced and its light-weight construction makes operation practically effortless.

Gorter attic ladders are load tested up to 450kg and thus suitable for practically any domestic or industrial application. Gorter attic ladders are suitable for suspended ceilings and can be supplied with a patented plenum system which spans the gap between the ceiling and roof whilst maintaining the gradient of the original attic ladder. Operation of the attic ladder requires less than 3kg of force and the adjustable anti skid steps and telescopic handrails ensure it is a safe and convenient access solution.

Gorter also supplies fixed step ladders, which are constructed from high strength hot dip galvanized steel and have large, anti skid horizontal steps and permanent handrails.

These ladders hook over a fixed step to secure them into place and can be also locked into place during use.

Gorter removable ladders and made from light weight but strong aluminium, have anti skid rungs and can be supplied with retractable handrails. Available for heights of up to 7.2metres, in single or sliding configuration, a Gorter removable ladder is a safe and cost effective alternative to expensive fixed ladders or stairways.

Floor doors are generally made from aluminium but can also be supplied in steel or stainless steel.
