A smooth steel step doesn't stay safe for long when there's water, oil, mud, or dirt around. That's why industrial stairways usually need more than a flat piece of steel. AMMS Global supplies stair treads in serrated bar grating and Grip Strut safety grating for factories, plants, platforms, walkways, and other access areas where people need solid footing.
If you're replacing damaged steps or specifying treads for a new staircase, send us the dimensions and application. We'll help you work out what type, material, and size make sense for the job.
What Are Stair Treads, Exactly?
The tread is simply the part of the stair you stand on. On an ordinary indoor staircase, that's a straightforward job. On an industrial staircase, the tread may have to deal with rain, oil, grease, dust, mud, heavy foot traffic, or all of them at once.
That's where open metal grating earns its place.
Instead of leaving water and debris sitting on a solid step, the openings allow them to pass through. Add a serrated or formed walking surface and you get better contact between the tread and the sole of a work boot.
It's a fairly simple idea, but it matters when the staircase is part of a working plant rather than a building entrance.
Serrated Bar Grating or Grip Strut?
These two types of metal stair treads do the same basic job, but their walking surfaces are quite different.
Serrated Bar Grating Stair Treads
Serrated bar grating stair treads use load-bearing bars with serrated tops. The serrations provide extra bite underfoot, while the open spaces between the bars allow water and loose material to fall through.
They're a practical choice for industrial stairs, access platforms, maintenance areas, walkways, and similar applications where you want a combination of traction and drainage.
Grip Strut Safety Grating Treads
Grip Strut uses a formed metal profile rather than the conventional bearing-bar arrangement. The surface has raised edges around the openings, giving footwear several points of contact.
That makes Grip Strut safety grating useful where slippery conditions are a regular concern. You'll often see this type of grating used on stairs, ramps, platforms, equipment access, and maintenance walkways.
Serrated Bar Grating | Grip Strut | |
Surface | Serrated bearing bars | Formed serrated openings |
Main feature | Grip and drainage | Strong underfoot traction |
Common use | Stairs, platforms, walkways | Stairs, ramps, maintenance access |
Construction | Open bar grating | Formed safety grating |
Why Use Anti-Slip Stair Treads?
A staircase beside a production line doesn't stay clean and dry all day. Someone might come down the stairs with wet boots, oil on their soles, or dirt picked up from the plant floor.
That's the situation anti slip stair treads are made for.
The surface gives footwear more to grip than a plain steel plate, while the open construction helps keep water and debris from building up on the step.
There's another practical benefit: you can usually see through an open tread. That makes it easier to spot dirt, damage, or anything that needs attention during routine inspections.
The actual tread should still be selected according to the conditions of the site. A dry warehouse and an outdoor chemical plant don't need the same specification.
Applications of Metal Stair Treads?
Industrial stairs show up in plenty of places that have little in common apart from needing reliable access.
AMMS Global stair tread solutions can be considered for:
Manufacturing and processing plants
Oil and gas facilities
Chemical and utility plants
Power generation facilities
Water and wastewater treatment sites
Warehouses and distribution centres
Industrial platforms and mezzanines
Maintenance and equipment access
Rooftop access
Outdoor stairs and elevated walkways
For outdoor or exposed installations, material and finish are just as important as the tread pattern. Rain is one thing; salt air, chemicals, and constant moisture are another.
Stair Treads Specifications
Don't start with the tread thickness. Start with the staircase.
The first thing we need to know is the required length and width. Then there is the support arrangement, expected load, tread type, material, and the environment where the staircase will be installed.
A few details make the specification much easier:
Dimensions: Length, width, and depth of the tread
Tread type: Serrated bar grating or Grip Strut
Material: Steel, galvanized steel, stainless steel, or the specified alternative
Load: Expected pedestrian and operational loading
Environment: Indoor, outdoor, wet, oily, corrosive, or chemical exposure
Fixing: How the tread will attach to the stair structure
If you're replacing an existing tread, the easiest option is often to measure what you already have. If you're working from drawings, send those instead.
Why Buy Stair Treads From AMMS Global
AMMS Global supplies industrial grating and access products for projects where standard building stairs aren't enough.
Our safety grating stair treads include serrated bar grating and Grip Strut options, so you can choose a walking surface based on the conditions rather than trying to make one product work everywhere.
We can work from your dimensions, drawings, material requirements, and quantity. That applies whether you need a small replacement order or treads for a larger industrial project.
Common Questions
1. What is the best material for stair treads?
That depends on where the stairs are going. Carbon steel works well for many general industrial applications. Galvanized steel is worth considering where additional corrosion protection is needed, while stainless steel makes more sense in environments where corrosion is a bigger concern. The site conditions should drive the material choice.
2. What do you call the metal strips on stairs?
The part you step on is called the stair tread. When it's made from grating, you'll also hear terms such as metal stair tread, grating stair tread, or safety grating stair tread. The front projecting edge of the step is the stair nosing.
3. What are the different types of metal stair treads available?
For industrial applications, serrated bar grating stair treads and Grip Strut safety grating are two common options. Serrated grating uses serrated bearing bars, while Grip Strut uses a formed anti-slip profile. The better choice depends on the staircase, environment, load, and level of traction required.
4. What is the typical thickness of steel stair treads?
There isn't a single thickness that works for every steel stair tread. It depends on the tread design, material, support spacing, span, and expected load. The thickness should be selected as part of the complete tread specification rather than simply choosing a standard number.
