Steel Grating Stair Treads

Steel grating stair treads are priced and fabricated by tread size, fixing method, nosing, side plate hole layout, surface and finish. Drawings help confirm fit with new or existing stair stringers.

RFQ quick details





**Tread type**T1/T2 plain tread, T3/T4 nosing tread, or project-defined fixing type.



**Tread size**Confirm clear width, tread length and bearing direction from drawing.



**Fixing holes**Welded or bolted fixing; confirm plate thickness, hole diameter and center distance.



**Nosing**No nosing, checker plate, serrated front edge or buyer-specified anti-slip nosing.



**Surface and finish**Smooth or serrated bars; hot-dip galvanized, painted or stainless finish.

Product overview

## Stair tread selection for fitted stair flights

Steel grating stair treads are fitted parts, so quotation should confirm more than the grating pattern. Tread width, length, nosing, fixing method, side plate holes and bearing direction all affect fit.

For new stairs, send the stair drawing or tread schedule. For replacement treads, include photos of the old tread, side plate holes and stringer spacing so the new pieces can match the existing stair.

 



### Stair Treads specification path

 

| Type reference | T1/T2 plain tread or T3/T4 checker-plate nosing tread. |
|---|---|
| Tread size | Typical widths: 600, 700, 800, 900 or 1000 mm; length follows drawing. |
| Nosing and surface | Checker plate nosing, serrated edge, smooth or serrated bearing bars. |
| Side plates | Confirm plate thickness, hole diameter, center distance and stringer layout. |
| Finish | Hot-dip galvanized, painted or stainless for indoor/outdoor exposure. |
| Packing marks | Mark size, type and quantity by stair flight or installation area. |

 

 





Standards reference

## Standards and finish references

- Stair access requirements may reference ISO 14122, OSHA walking-working surface rules, AS 1657 or local site standards.
- Steel grating construction can be reviewed with YB/T 4001.1, ANSI/NAAMM MBG 531 or BS 4592 when specified.
- Hot-dip galvanizing can follow ISO 1461 or ASTM A123/A123M when a zinc coating reference is required.
- T1/T2/T3/T4 names are useful quotation shorthand; final tread size, side plate holes and fixing method should follow approved stair drawings.

 



Specification examples

## T1-T4 tread type reference

 

| T1 welded plain tread | Welded fixing, no checker plate nosing; weld position follows drawing. |
|---|---|
| T2 bolted plain tread | Side plates with bolt holes, no checker plate nosing. |
| T3 welded nosing tread | Welded fixing with checker plate nosing for front-edge contact. |
| T4 bolted nosing tread | Side plates, bolt holes and checker plate nosing. |

Use T1-T4 as RFQ shorthand. Final fixing, nosing, hole layout, load and finish should follow drawings.

 

 





Component reference

## Stair tread parts to confirm before production

Carrier plates, also called side plates, are confirmed by drawing together with bolt holes, nosing type, bar grating direction and final finish.

- Confirm side plate hole size and center distance.
- Choose plain edge or checker plate nosing by project requirement.
- Match bar grating direction and tread width to the stair drawing.
 
 

 

 

 

 

 



Applications

## Stair tread project photos and packing references

Use these project views to check installed tread appearance, checker plate nosing, stair flight grouping and packing marks before quotation.







### Installed tread flight view

Installed grating treads show checker plate nosing, open-grid walking surface and stair fit-up.









### Project stair replacement view

Existing stair photos help confirm tread width, nosing style, bearing direction and stringer spacing.









### Packed by stair number

Bundle labels, tread quantities and stair flight marks help organize installation after shipment.







 

 

 





RFQ checklist

## Send the tread details that affect fit and price

For stair tread quotation, send the tread schedule or stair drawing with width, length, fixing method, nosing, side plate holes, surface, finish, quantity and destination. Replacement photos help when matching old stringers.

FAQ

## Stair Treads buyer questions

 

What sizes do steel grating stair treads come in?

Typical tread widths are 600, 700, 800, 900 and 1000 mm. Tread length and depth follow your stair drawing or tread schedule.



What do the T1, T2, T3 and T4 tread types mean?

T1 is a welded plain tread, T2 a bolted plain tread with side plates, T3 a welded tread with checker plate nosing and T4 a bolted tread with side plates and checker plate nosing.



Do treads come with side plates (carrier plates)?

Yes. Side plates are made to your drawing; confirm plate thickness, bolt hole diameter, hole center distance and stringer layout.



Do I need checker plate nosing?

Checker plate nosing gives a solid, more visible front edge where feet land. Choose plain or checker plate nosing according to your project requirement.



Can you match replacement treads for an existing stair?

Yes. Send photos of the old tread, the side plate holes and the stringer spacing, with measurements, so the new treads fit the existing stair.



Which finish should stair treads have?

Hot-dip galvanized treads are common outdoors, painted treads suit dry indoor stairs and stainless steel is used in corrosive areas. Serrated bars add grip on wet or oily stairs.



Which standards apply to grating stair treads?

Projects often refer to ISO 14122, OSHA walking-working surface rules, AS 1657 or local codes. Final tread size, holes and fixing follow your approved stair drawings.



Can treads be packed by stair flight?

Yes. When you provide a tread schedule, bundles can be marked by size, type and stair flight to make site installation easier.
