Ladders — Stein Service & Supply

Rolling Ladder Services

We size each ladder from the highest shelf to be reached and recommend the type for the aisle where it will be used.

Most of our work is in North Carolina, South Carolina, Georgia, and Virginia, and in 2025 we completed projects in 24 other states.

Rolling Ladder Sizing

Sizing starts at the highest shelf or access point to be reached. The top platform should be within 5 feet (60 inches) of that point, so the platform height is that height minus 60 inches. Steps rise 10 inches, so the number of steps is the platform height divided by 10.

Platform Height

60in

Below the highest point to be reached

A top shelf at 150 inches (12½ feet) requires a platform at 90 inches.

Number of Steps

10in per step

Platform height divided by 10

A 90-inch platform requires 9 steps.

When the result falls between two sizes, select the larger ladder. The smaller ladder places the platform more than 5 feet below the top shelf, and the user must overreach. How to choose a rolling ladder

Types of Rolling Ladders

Once the height is set, the type depends on the aisle and the work done from the ladder.

Type	Use
Square and round tube industrial	The rolling ladder we supply most often. For stockrooms, maintenance, and shop floors.
EZY Climb incline	A 50-degree incline with deeper steps, so the climb is closer to the motion of climbing stairs.
360 rotating	Rotates in any direction for narrow aisles. Available at a 60-degree incline for a smaller footprint, or at 50 degrees.
Stock picking	A cart and a ladder in one unit, so a picker can collect several items from the shelves in one trip.
Folding	Folds into a compact package for storage or transport. Assembly requires 4 screws.

Standard Rolling Ladder Specifications

Feature	Standard ladder
Capacity	450 pounds, one person
Frame	Welded 1-inch steel tube
Width	16, 24, or 30 inches on most models
Steps	7 inches deep, with a 9½-inch top step
Movement and locking, 1 to 7 steps	3-inch spring-loaded casters for movement, and rubber tips that hold the ladder in place during use
Movement and locking, 8 to 16 steps	EZY-Lock, which rolls the ladder and locks it in place for use
OSHA	Meets or exceeds the OSHA walking-working surface rules in Title 29 of the Code of Federal Regulations, Part 1910 (29 CFR 1910). These rules require slip-resistant steps and a ladder that supports 4 times its rated load.

A wider base reduces sway, so the widest ladder that fits the space is the most stable. The aisle must still allow people to pass the ladder, and the ladder must clear the corners and doorways on its route and have a storage location.

Tread Options

The floor conditions where the ladder is used decide the tread.

Perforated EZY Tread

A perforated tread formed from a solid steel sheet. It grips the sole and still allows the foot to move. Suitable for clean or standard-duty areas, it lasts longer than rubber-type treads.

Grip Strut

Serrated, galvanized grating that grips footwear in every direction and resists rust. The open pattern is easy to clean. For wet or oily floors and for ladders used outdoors.

Vinyl

A solid, textured, slip-resistant step that is softer underfoot. For users who prefer to stand on a solid surface.

Rolling Ladder Questions

How often should a rolling ladder be inspected?

Before every use. Check for missing parts, bends, cracks, rust, loose bolts or rivets, broken welds, and bent caster wheels. Confirm that the lock works and that the ladder does not rock on a level floor. A ladder tagged “do not use” stays out of service.

What should ladder users be trained on?

Users keep three points of contact with the ladder, stay centered between the rails, and face the ladder on a steep climb. The ladder is set on level ground as close to the work as possible, so that no one overreaches. Most ladder injuries occur while a person carries a load on the steps, so heavy items are lifted up separately.

Is a rolling ladder safer than a stepladder or an extension ladder?

Yes, for warehouse work. A rolling ladder is sturdier than an extension ladder and more stable than a folding stepladder. It has handrails along the steps and around the platform, and a lock that keeps it from rolling while it is in use.

How should a rolling ladder be maintained?

Keep the ladder clean and store it in a dry location, because oil and caustic chemicals make the steps slippery and corrode the metal. Do not store items on the ladder, and replace parts as they become worn. Rolling ladder best practices
