ROOF STAIRWAYS
ALUMINIUM STEP ACCESS SYSTEM COMBINED WITH ROOF GRIP WALKWAY LEVELING BRACKET SYSTEM
STEP TREAD
ROOF STEP ACCESS TREADS ARE MANUFACTURED USING EXPANDED ALUMINIUM ALLOY FLOOR GRATING. THE NON-SLIP SURFACE TEXTURE OF THE FLOORING ADDS TO THE SAFE USE OF THE PRODUCT.
THE LOAD CARRYING BEARER IS A 13 x 4.75mm FLAT BAR. THESE ARE JOINED TOGETHER BY A INTEGRATED WEB. NO WELDING IS INVOLVED IN THE MANUFACTURE OF THE FLOOR GRATING.
STEP UNIT
EACH STEP UNIT CONSISTS OF 2 TREADS. THE UNITS MAY BE FITTED SINGILUARLY OR FIXED TOGETHER USING A FISH PLATE. THE TREAD CAN BE PIVOTED AT THE BACK OF ASSEMBLY, BY CHANGING THE LENGTH OF THE FRONT POST WE CAN ADJUST THE ANGLE OF THE TREAD TO SUIT THE ROOF.
THE STEP UNIT IS FIXED TO THE ROOF SHEET USING A SPECIALLY DESIGNED BRACKET THAT INCLUDES A FIXING, EITHER A SEAM CLAMP OR BONDED CAP, THAT MATCHES THE ROOF SHEET PROFILE.
THE SPACING OF THE BRACKETS IS DETERMINED BY THE ROOF SHEET PROFILE.
WHILE ROOF STEP IS LAYED UP THE ROOF SLOPE, IN LINE WITH THE SHEETING RIDGE, THE LEVELLED ROOF GRIP IS LAYED HORIZONTALLY ON THE ROOF, I.E. ACROSS THE ROOF SHEET RIDGE.
LEVELLED WALKWAYS HAVE LEVELLING BRACKETS THAT ARE DESIGNED TO SUIT THE PITCH OF THE ROOF AND THE WIDTH OF THE WALKWAY. SEAM CLAMPS ARE USED TO SECURE THE BRACKETS TO THE ROOF.
A PURPOSE MADE ALUMINIUM HANDRAIL IS AVAILABLE FOR WALKWAYS THAT ARE INSTALLED CLOSE TO A FALL EDGE. THE STANCHION SPACING IS DETERMINED BY THE RIDGES ON THE ROOF SHEET PROFILE.
ROOF STEP IS NORMALLY COMBINED WITH ROOF GRIP ACCESS WALKWAYS THAT HAVE BEEN LEVELED TO GIVE A SAFE AND COMFORTABLE WALKWAY.
