Type T1 — welded fixing, no nosing guard
Tread welded directly to the stringer; the economical choice for permanent industrial stairs where a nosing guard is not required.
Engineered Around Your Load & Span
Stair Tread Grating
Stair tread grating combines a grating panel with a slip-resistant nosing, carrier end plates and fixing holes, ready to bolt or weld to industrial stair stringers. The open grid drains water and sheds debris while the nosing defines the step edge — supplied in standard T1–T4 types or fabricated to your stair drawings, galvanized, stainless or aluminum.
- Checkered, abrasive or serrated nosing options
- End plates with standard or custom hole patterns
- T1–T4 standard types or made to stair drawings
- Galvanized carbon steel, stainless steel or aluminum

What is stair tread grating?
A grating stair tread is a rectangular grating panel fitted with a nosing along the front edge and carrier end plates or angles at both ends. The open grating drains water and sheds debris, while the nosing defines the step edge, improves grip and gives climbers a clear visual cue.
Treads are specified by grating type, tread width and length, nosing type, end-plate fixing and hole pattern. Common industry types T1 to T4 combine welded or bolted fixing with or without a nosing guard — we manufacture these catalog types and fully custom treads detailed from your stair arrangement drawings.

Variants
Recommended Types
Type T2 — bolted fixing, no nosing guard
Carrier end plates with round or slotted holes bolt to stringer brackets, allowing tread removal for maintenance.
Type T3 — welded fixing, checkered-plate nosing
Permanent fixing plus a nosing guard that defines the step edge and improves grip — the common outdoor standard.
Type T4 — bolted fixing, checkered-plate nosing
Removable treads with nosing guard, used where stairs need both slip protection and maintenance access.

Fabrication & Quality Notes
- Treads are cut from welded grating, then fitted with nosing and carrier end plates to drawing.
- Hole patterns are drilled to your stringer dimensions — round or slotted holes allow site tolerance.
- Each tread is checked for width, length, hole centers, squareness and nosing alignment.
- Nosing is welded along the full front edge; welds are dressed before galvanizing or passivation.
Packaging
Packaging & Delivery
- Treads nested and strapped in bundles with edge protection on nosings.
- Bundles labeled by stair flight or area code to match installation sequence.
- Galvanized treads packed with ventilation spacing to reduce wet-storage staining.
FAQ
Stair Tread Grating FAQs
What information is needed to order stair treads?
Tread width and length, grating specification or load requirement, nosing type, end-plate hole pattern (or stringer details), quantity and finish. Stair drawings are ideal.
Which nosing should I choose?
Abrasive or serrated nosings give the best grip outdoors; checkered plate nosing is the economical standard. We can advise based on environment and traffic.
Can treads be bolted instead of welded?
Yes. Bolted end plates with slotted holes allow removal for maintenance — provide your stringer spacing and hole preferences.
What do T1–T4 stair tread types mean?
Catalog shorthand combining fixing and nosing: T1 welded without nosing guard, T2 bolted without nosing guard, T3 welded with checkered-plate nosing, T4 bolted with checkered-plate nosing. We also manufacture fully to your own tread drawings.
Is there a standard tread width or length?
Treads are made to your stair design; common widths run about 200–300 mm and lengths follow the clear distance between stringers. Send the stair drawing or stringer dimensions and we will detail the full set.
Can you match treads to existing stringers?
Yes. Measure the length between stringers and the hole centers on the existing end plates, or send photos with dimensions — we will match the carrier plates and hole pattern.
What are the MOQ and lead time for stair treads?
Treads are produced to order — small batches for a single stair flight are acceptable. Typical lead time is 15–25 days including galvanizing; sample treads of standard types take 3–7 days.
