Open-Type Flange-Mounted Pool Ladder (AISI 304)

The Open-Type Flange-Mounted Pool Ladder (AISI 304) is bent from Ø43 mm AISI 304 stainless steel tube and supplied 51 cm wide, together with escutcheons and mounting parts. In the Open-Type ladder, the long handrails clear the overflow channel and grating at the edge of overflow pools with a horizontal reach of E = 870 mm and are fixed with flange connections to the deck behind the channel; this means no anchors need to be drilled into the overflow channel or the grating. The ladder body rests against the pool wall via flanged spacers on the handrails (distance from wall F = 180 mm, handrail centre distance G = 500 mm). The overall height A rises from 1570 mm (2 steps) to 2320 mm (5 steps) depending on the number of steps; the height above deck B is 710 mm.

For each number of steps there are three step types: stainless steel anti-slip steps (ATS HKE013–016), stainless steel steps (-S codes) and plastic steps fitted to the stainless steel frame (-P codes). The step spacing is a constant C = 250 mm; depending on the number of steps, the in-pool depth dimension D rises from 690 mm (2 steps) to 1440 mm (5 steps). The ladder is chosen according to pool depth: the bottom step should remain at a depth where the user can step on it comfortably without reaching the pool floor.

AISI 304 (1.4301) grade is an economical and practical choice for residential, villa and hotel pools using chlorine disinfection. For salt-electrolysis, seawater-fed, thermal or heavily chlorinated indoor pools, the molybdenum-bearing AISI 316 version is recommended against chloride-induced pitting corrosion.
