CONTACT · TIANJIN SALES DESK
Talk to the people who will actually quote you.
Three channels, all reaching the same desk. WhatsApp is fastest for drawings and site photos; email suits purchase orders and documents; the RFQ builder writes one enquiry you can send through either.
Direct channels
| Channel | Detail | Best for |
|---|---|---|
| +86 138 2093 3987 | Drawings, site photos, quick dimension checks | |
| 2268199197@qq.com | Purchase orders, documents, formal quotations | |
| Telephone | +86 150 2264 1456 | Urgent loading or inspection questions |
| RHCY1658 | Domestic buyers and existing customers |
Business hours: Monday–Saturday, Tianjin time (UTC+8). Messages outside those hours are answered the next working morning.
Two personal WeChat accounts. Open WeChat, scan either code, and send a friend request — the desk accepts during Tianjin business hours (Mon–Sat, UTC+8). If WeChat is restricted where you work, use WhatsApp or email above; they reach the same desk.
WeChat is a China-first channel
Most overseas buyers reach us faster on WhatsApp. WeChat stays on this page because Chinese-speaking staff, existing customers and inspection agents use it for photographs and loading updates.
Before you write
A useful first message answers four questions. Everything else can follow.
- Where is the site — country, region, and the nearest port you would use.
- What is the covered area, the span and the bay length you have in mind.
- What snow and wind figures must the frame carry — or which code your engineer works to.
- What you need from us: frame only, frame plus covering, or a complete house.
If you do not have the numbers yet
Send a photo of the plot and a rough width. We will come back with two or three reference configurations and the questions your engineer needs to answer. That is a normal first round, not a sign of an unprepared buyer.
What happens after you send
Same-day read
We confirm we received it and name the person handling the file.
One round of questions
Usually two or three points on loads, covering or packing — sent in one message, not five.
Quotation
Frame schedule, weights, price, lead time, Incoterm, loading plan.
Samples and certificates
Mill certificate and packing photos before shipment; third-party inspection if you appoint one.
Who you are contracting with
The commercial seller is Tianjin XinYonSen Agricultural Technology Co., Ltd. The production entity and the holder of the mill and management certificates is Tianjin Pufeng Iron & Steel Co., Ltd., whose works are in Daqiuzhuang, Jinghai District, Tianjin. Both names appear on the footer of every page of this site and must appear on the purchase order.
Address
No.51 S213 Provincial Road, Daqiuzhuang Town, Jinghai District, Tianjin, China. Visits and third-party inspections are welcome with two working days' notice so the line and the certificate originals are available.

Send the drawing on WhatsApp
A phone photo of a marked-up print is enough for a first price. We will tell you what is missing.
