Heavy-Duty Platform Step Ladder
Our heavy-duty platform step ladders are available in a choice of sizes, from 3 treads to 12, making these perfect for a wide variety of uses, domestic and commercial.

(orders over £25 + vat)

While the smaller versions are often found at home, in shops, offices and storage facilities, the larger versions are common in warehouses, industrial environments and are used by tradesmen. Now with an integrated tool tray and hook, this saves you climbing up and down your ladder to get supplies, making it easier to work at height.
The classic Class 1 step ladder provides strength and quality. With a reinforced 330 x 255 checker-plate platform, the 85mm riveted treads ensure it’s comfortable to stand on for extended periods, while the hinged metal locking stays provide optimal stability. Built from aluminium, these ladders are sturdy without being bulky or heavy, with slip-resistant feet and a strong box section construction designed to take on heavy-duty bracing.
Perfect for commercial light trade work and heavy-duty DIY use, the heavy-duty Class 1 platform step ladder is manufactured in the UK by TB Davies to the new EN131 Professional ladder standard and has a maximum user weight of 150kg (that just over 23 stone).
