Supply scope
What One Grating Supplier Should Cover
A supplier is more than a price on a panel. When buyers shortlist metal bar grating suppliers, they are really comparing the same six things this page measures — and this is how a factory-direct mill, a trading company and a local stockist compare on the six things a grating program actually depends on, with an honest note on where each model fits.
| Dimension | Factory-Direct Supplier | Trading Company | Local Stockist |
|---|---|---|---|
| Who makes your panels | The same workshop that quotes — Dengtai Staircase Manufacturing Co., Ltd. | A mill you rarely meet; the contract sits with the broker | Whatever mill filled the warehouse |
| Range across the catalog | Four product lines, custom fabrication, and companion fixings sourced alongside panels | Broad on paper; depends on partner mills that week | Standard catalog sizes only |
| Custom sizes | Cut and banded to your drawings, free review inside the quote | Possible, with an extra margin layer | Rarely offered |
| Documentation | MTC EN 10204 3.1, inspection report and DoC per destination with every order | Varies with the mill behind the order | Rarely traceable to the heat |
| Lead times | Samples 5–7 working days, production 15–25 after drawing confirmation | Mill time plus broker handling | Bound to warehouse stock |
| Reorder consistency | Same lines, same five-stage QC, same MTC discipline on every repeat | Spec can drift if the broker switches mills | A reorder can mean a new source |

The supply path
From Drawing to Container
1 · Drawing & spec review
Send drawings, photos or a sketch. Review is free, and an itemized quote follows within 24 hours — from the workshop that will run the job.
2 · Samples in 5–7 days
Working days, hot-dip galvanizing included — prove the spec, the packing and the paperwork on a small trial order before you scale.
3 · Production in 15–25 days
Working days after drawing confirmation, under five-stage QC — from MTC verification at goods-in to final inspection before release.
4 · Packing & export
Export packing on steel straps and pallets, FOB Tianjin from a mill about 400 km from the port. DoC, MTC and inspection report travel with the shipment.
Why buyers stay
Why Buyers Make Dengtai Their Grating Supplier
One-stop across the range
Welded, press-locked, stair tread and stainless lines, custom fabrication to drawings, and companion clips and fixings sourced alongside our panels — one purchase order, one container, one supplier to hold to it.
No middlemen, export-ready
Factory-direct FOB quotes come from the workshop that runs your job. Export documentation is prepared per destination before the container is sealed — not patched together after sailing.
Quick replies, flexible scheduling
A small team that answers fast: quotes within 24 hours, small trial orders welcome, and scheduling that bends around your program instead of the other way around.

- Factory inspection report with every shipment
- Declaration of Conformity prepared per order destination
