WALKWAY PANELS
ROOF GRIP ACCESS WALKWAY SYSTEM FLOOR PANELS ARE MANUFACTURED USING EXPANDED ALUMINIUM ALLOY FLOOR GRATING. THE NON-SLIP SURFACE TEXTURE 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.
FIXING BRACKETS
THE FLOOR GRATING PANEL IS FIXED TO THE ROOF SHEETS USING AN ELEVATED BRACKET SYSTEM. THIS ALL ALUMINIUM ALLOY BRACKET HAS BEEN SPECIALLY DESIGNED AND ITS USE HAS BEEN APPROVED BY ALL THE MAJOR ROOF SHEET MANUFACTURERS.
THE FLOOR GRATING PANEL IS CARRIED BY THE BRACKET THROUGH A BEARER BAR THAT IS ATTACHED TO A SEAM CLAMP, FIXED TO THE ROOF SHEET. EACH ROOF SHEET PROFILE HAS A SPECIFIC CLAMP DESIGN.
THE SPACING OF THE BRACKETS IS DETERMINED BY THE ROOF SHEET PROFILE AND THE DESIGN LOAD CARRYING REQUIREMENT OF THE WALKWAY SYSTEM.
CONNECTIONS AND INTERSECTIONS
LINEAR JOINTS
ROOF GRIP ACCESS WALKWAY LINEAR JOINTS ARE EFFECTED USING A SIMPLE H CONNECTOR. THE SAME CONNECTION APPLIES WHETHER THE SYSTEM IS BANDED OR NOT. THE H CONNECTOR IS FIXED ONE SIDE ONLY TO ALOW FOR ANY MOVEMENT DUE TO EXPANSION OR CONTRACTION. AN EXTRA SUPPORT BRACKET MAY BE REQUIRED TO STIFFEN THIS CONNECTION.
CORNER JOINTS
AT EVERY CORNER ONE WALKWAY SEGMENT WILL BE FULL LENGTH AND THE OTHER WILL BUTT UP AGAINST IT. WHERE THIS BUTT JOINT TAKES PLACE AN H CONNECTOR IS FITTED TO ENSURE A SEEMLESS CONNECTION.
TEE JOINTS
WHERE ONE WALKWAY BUTTS UP TO ANOTHER WALKWAY AND A TEE JOINT IS FORMED WE FIX AN H CONNECTOR ON THE INTERSECTING WALKWAY. THIS ENSURES A SAFE, LEVEL ACCESS SYSTEM.
WALKWAY OVER FLASHING
WHEN A WALKWAY CROSSED OVER FLASHING THE BEARER IS FITTED IN THE SAME MANNER AS USUAL, HOWEVER THE CLAMP IS REPLACED WITH AN ALUMINIUM SPACER. THE SPACER MAY BE BONDED TO THE FLASHING TO ELIMINATE ANY MOVEMENT.
