Sourcing comparison
Factory-Direct from China vs US Distributor vs Trading Company
Most lists of steel grating manufacturers USA buyers find online mix three kinds of seller. Here is the honest comparison — including what we are, and what we deliberately are not.
| Dimension | Factory-direct from China | US distributor | Trading company |
|---|---|---|---|
| Where you buy | Our own workshop in Shijiazhuang, China | A domestic warehouse or service center | An intermediary reselling factory output |
| Price layers | One factory price, itemized per line | Mill price plus distributor margin | Factory price plus trader margin |
| Product range | Four product lines, made to order | Stocked designations from the shelf | Whatever the represented mill builds |
| Custom panels | Cut and banded to your drawings | Limited to stocked sizes | Passed on to a third factory |
| Verification | Audit the mill before you order | Sales representative visit | Second-hand claims |
| Paper trail | MTC 3.1, inspection report, DoC per destination | Domestic paperwork | Varies by seller |
One thing a China factory cannot offer is a warehouse on your side of the Pacific — so we do not pretend to. Panels ship by container from Tianjin, and the ocean leg is planned into your schedule, not hidden from it. Send your drawings — we will price the whole path inside the 24-hour quote.
How it works
From RFQ to a Container at a US Port
Send your RFQ
Panel sizes, designations or drawings, quantities and your destination port. Drawing review is free — sketches and photos are enough to start.
Itemized quote in 24 hours
FOB Tianjin as standard, EXW or CIF to your port on request. Small trial orders are welcome — you do not need a full container to begin.
Samples in 5–7 days
Check welds, mesh and galvanized finish in your own hands before you commit — hot-dip galvanizing already included in the sample window.
Production in 15–25 days
Working days after drawing confirmation. Then container loading at Tianjin Port, roughly 400 km from the mill, export documents attached.
Why buyers stay
Why US Buyers Work With This Factory
Suppliers USA, no middlemen
You quote with the workshop that cuts, welds and inspects the panels — not a reseller marking up a catalog. Factory-direct means the price you get is the price we build to.
One-stop, four product lines
Welded, press-locked, stair treads and stainless grating from one supplier — one quote, one inspection standard, one container instead of three consolidations.
Quick replies, small MOQ
English-speaking sales answer in writing within 24 hours, and small trial orders are welcome. Flexible scheduling on a small-team shop — your urgent panels are not queue filler.
Product range
The Four Lines US Buyers Source From Us
One factory, four grating families — platform and walkway panels, trench covers, stair treads and stainless duty, all cut to your drawings.
Welded steel bar grating
Bearing bars 20×3 mm to 100×8 mm on 30 / 40 / 60 mm centers — the 19W4-style workhorse for platforms, walkways and trench covers.
Press-locked grating
No-weld close mesh down to 11 / 11 mm — flat panels for municipal trench, tree pits, facades and fine pedestrian floors.
Stair treads
Cut, banded and nosed treads, serrated or plain, quoted with OSHA loading context for industrial and escape stairs.
Stainless steel grating
SS304 and SS316 panels on the same dimensional range — food plants, chemical areas and coastal duty where carbon steel will not last.

Documents that travel with your container
Importing means paperwork, and the paperwork comes from the mill, not from a reseller. Every shipment leaves with:
- Mill test certificate to EN 10204 Type 3.1
- Declaration of Conformity prepared per destination market
- Factory inspection report with every shipment
- Installation drawings and fixing layout for bolted assembly
Verification
Vet Us Before You Commit a Container
Factory audits accepted
Visit the workshop in person or send a third-party inspector — audit files on demand, and your auditor sees the same lines that build your panels.
Five-stage QC
MTC verified at goods-in, first-article check, weld inspection on the panel, coating thickness sampling after galvanizing, final inspection before loading.
Tested, with reports on request
CE & SGS tested, reports on request — documents you can verify yourself, not a certificate wall. Ask in your quote and the files come with it.
US buyers
Serving US Buyers Factory-Direct from China
Let us be plain about what this page is: Dengtai has no US address, no US warehouse and no stock held on your side of the Pacific. What we offer instead is a direct line to the mill — and a buying process built for the distance.
English-speaking sales
Quotes, drawings and documentation handled in writing by our own export team — no translation layer between your spec and the shop floor.
The time difference, working for you
Questions sent at the end of your US day are answered by our morning in China — replies and updated quotes waiting in your inbox when you start work.
Containers from Tianjin to US ports
The mill sits roughly 400 km from Tianjin Port. FOB Tianjin as standard, CIF to your port negotiable — loading plans calculated so you pay for the steel you ship, not wasted container space.

FAQ
Frequently Asked Questions
Do you have a warehouse or office in the USA?
No — Dengtai has no US warehouse, no US office and no US sales company, and we do not claim one. You buy factory-direct from our workshop in Shijiazhuang, China, and panels ship by container from Tianjin Port. English-speaking sales handle quotes, drawings and documentation by email and WhatsApp.
Can a US buyer start with a small trial order?
Yes — small trial orders are welcome before you commit to a full container. Sample panels ship in 5–7 working days, and repeat production runs 15–25 working days after drawing confirmation, hot-dip galvanizing included.
What documentation ships with grating orders to the United States?
Every order travels with a mill test certificate to EN 10204 Type 3.1, a factory inspection report and a Declaration of Conformity prepared for the destination market. Welded panels are produced with ANSI/NAAMM MBG 531 as reference practice and stair treads are quoted with OSHA loading context — reports on request.
