A-Mezz Industrial Structures, Inc.

Sometimes you don't have enough room for a full size stair, but you don't want to use a 90 degree safety ladder because you want an easier climb. For those instances you can use a ships ladder (sometimes called ships stairs). Ships ladders have a safe climbing angle between 50 and 70 degrees and have ladder safety rails on both sides. Those ladder rails can terminate with the top tread for use as a roof hatch access ladder, or can extend above the top tread like the handrail on a standard stair design.OSHA fixed ladder requirements do not pertain to ships ladders and neither do OSHA stair requirements. You can see the details in the letter from OSHA below the ships ladder sketch below.The treads on a standard steel ships ladder are up to 12 apart and 24 wide, but this can be adjusted stair to stair depending on requirements. They can be done as either closed diamond plate stair treads or bar grating treads, but the bar grating tread is the standard option due to its superior slip resistance, self-cleaning design and economic price.To order a ships ladder we will need to the dimensions of (A) and (B) below. Standard finish is black grating treads and gray stringers and handrail. We can also provide ships ladders in a custom paint color or hot dipped galvanized

A-Mezz fixed ladders and cages are heavy-duty, safe and strong. We have OSHA-compliant access ladders for nearly any structure, from walls and warehouses to silos bridges and roof hatches.Our steel ladders and cages are coated with a tough powder coat finish. Choose from 11 colors including gray, black, safety yellow, beige and brown. Mill finish aluminum, stainless steel and hot dip galvanized options are also available.Fixed ladders can be customized with:Longer standoff brackets to clear roof gutters, flashing, coping, conduit and other obstructionsStep across platforms and parapet crossover rails for tall (greater than 14") parapets, gutters that extend more than 5" from the wall, wall crossovers, and areas where the step across distance from the ladder rung to the nearest step-off point is greater than 12".Lockable security rung door at the bottom ladder rungs or bi-parting lockable cage doors at the bottom of cages are available for increased safety and security. They help to prevent unauthorized ladder access by both inquisitive children as well as criminals such as copper thieves. Loose standoff brackets for bolting or welding onto the fixed ladder in the field for flexibility with mounting locations and lengths because not all mounting locations are clear smooth walls. Modular construction of 7' or smaller sections for the ladders and cages for tough to get to install locationsBolt on floor mount brackets for increased stability and strengthIncreased side member sizes for extra heavy duty access needs.
