Gorter roof hatches come with a TÜV NORD certificate, Aboma safety mark and KOMO® certificate. The hatch cover also has a fully windproof double sealing around it, and the RHT roof hatch has a euro cylinder lock. Above a length of 1,501 mm, the Gorter RHT roof hatch even has a three-point lock. The glazed RHTG roof hatch is opened and closed by two powerful and compact electric motors.

What is a Gorter hatch combination

With a Gorter combination, you have a total solution for roof access from the top storey of a building. A Gorter combination consists of a roof hatch with matching scissor stair, ladder or fixed staircase. The roof hatch and accompanying ladder/stair are designed to suit each other completely. The combinations are also TÜV NORD-certified and you can back up your RIE (Risk Analysis and Assessment) with the documentation supplied.

Fixed staircase

The Gorter fixed staircase is made entirely from anodized aluminium. The choice of material and the design give the staircase a very contemporary and modern look.

Ladder

Depending on the floor height, the Gorter push-up and extension ladders are available with a single, double or triple extension ladder.

 

Scissor stair

A complete scissor stair consists of a casing and wooden cover underneath. The handrail is supplied separately and is easy to fit.

 

Floor doors

Floor doors from Gorter Luiken are available in a wide range of versions: with hinged and removable covers, in aluminium or steel, or suitable for upholstering/tiling. With the exception of surface-mounted versions, most floor doors lie flush with the floor surface and can be used inside and out.

 

Floor doors can be combined with a Gorter stair or ladder. The range of applications is enormous. Floor doors are ideal for providing access to underfloor areas such as tanks, wells, service ducts, other floors, etc. in residential and non-residential buildings. One or two floor door covers are fitted, depending on the dimensions.
