Where routine access is required, either as a means of fire escape or steps between roof levels, we can offer a variety of single and multi-flight industrial stair solutions in aluminium or mild steel.
Where the presence of roof mounted ventilation equipment or plant renders areas inaccessible, bridging steps offer a versatile solution. These combined stair and platform units enable personnel to traverse safely up and over any pipe work or similar obstruction to access all roof areas for maintenance and cleaning.
Rostek Ship Ladders
‘Ship ladders’ are ladders with a pitch of 65-75° that are fitted with treads. Where design parameters permit, they are more practical to use than vertical ladders.
Ship ladders should not exceed three metres vertically, should be fitted with a single line of handrail on each side and require a width between 450mm and 550mm.
The height of the handrail should range between 250mm for a ladder slope of 65° and 100mm for 75° slope. The top tread should be at the same level as the adjacent floor, with a minimum tread width of 100mm, minimum rise of 225mm and maximum rise of 255mm.
Rostek Cat Ladders
Cat Ladders are permanent, vertical fixed ladders, with a slope range from 75° to vertical and are most commonly used on the outside of structures to gain access to roofs or between roof levels on larger buildings.
Made from aluminium, galvanized or stainless steel, we can design, manufacture and install cat ladders to almost any size, from two to 25m, complete with landings and safety hoops.
