AA720 Mild Steel Access ladders are designed for access to platforms and structures where the use of a stair is not suitable.
Prashaant Steel & Alloys is a leading producer of Mild Steel Rungs and a high-calibre retailer. Our mild steel fixed ladders are a cost-effective and economical system based on the modular principle: components coordinated with one another can be combined in a number of different ways to ensure flexible adaptation to any application. This means that in many cases you can save yourself the expense of a one-off special job. All components and versions can be supplied ex-stock. We shall be pleased to assist you with our comprehensive consulting services and put a system together for you that meets your requirements perfectly.
Ladders are 380mm min between stringers, complete with rungs at 300 max ctrs. For the AA720 ladder type, the stringers are opened out to 700mm to a walk-through and is complete with a three rung step section. For ease of transport/installation, ladders can be spliced.
Ladders are secured with stays at generally 2500 ctrs, although this may increase if larger stringer sections are used. Safety cages or fall arrest systems are an essential requirement for ladders where a user could fall 3m or more or come into contact with dangerous equipment.
Safety cages should start 2400mm from FFL and have hoops in line with the handrail cars to the head and 900mm max spacing there-after. Inclined ladders should be set at 75 ̊ or steeper. Landings, where required, should not be less than 840mm square complete with handrails and toe plates to protect open sides.
