Factory Tour · Tianjin Founded in 1996, Tianjin Huizhong Xinyu is headquartered in the Daqiuzhuang Industrial Zone, Jinghai District, Tianjin, widely recognised as one of the largest and most complete steel industry hubs in the world. Being inside this cluster gives our buyers direct access to rolling mills, pipe plants, galvanizing lines and coating workshops within a short trucking radius.
We operate production bases in Tianjin and Tangshan covering 1,500 acres and integrate R&D, production, deep processing and export under one company, so specification, inspection and logistics are handled by the same team from order to port.

Honesty, integrity and win-win cooperation have guided our export business for more than two decades. Here is what that means for your next purchase order.
Replace five or six suppliers with one. HZXY covers the structural, reinforcement and MEP materials of a typical building or infrastructure package:
Year-round stock of hot-selling sizes on a 1,500-acre base lets us handle bulk tenders and rush orders without waiting for a new mill cycle.
Materials comply with international standards and ship with complete test reports and qualification documents, ready for consultant and customs review.
Cutting, bending, welding, galvanizing and spraying in-house, with non-standard sizes available across every product line.
Experts in Incoterms, L/C and T/T documentation and international logistics, with a dedicated coordinator tracking your order end to end.
More than 10 million tons of annual capacity and long-term partnerships with distributors and contractors across Africa, the Middle East, Southeast Asia, Latin America and beyond have earned HZXY repeat business built on consistent quality and attentive service.
Section steel, rebar, plates, steel pipes, plastic pipelines and valves engineered for the sectors our customers build every day.
Workshop columns, roof girders, load-bearing frames, main girders of bridges and viaducts, and heavy machine and vehicle frames.
Reinforcement cages for water-conservancy projects, concrete rebar and main bars for foundation pile caps.
Thick plates for decks and hull sides, body panels and machinery sheet.
Civil, municipal and farm water networks plus power and telecom cable protection.
Galvanized steel pipe, water supply and gas transmission pipes and matching valves for fire mains, sprinkler loops and municipal utility pipelines.
Customization and processing in-house: cutting, welding, bending, stamping, drilling, galvanizing and coating, so material arrives on site matched to your drawings.
Steel sections and pipes are cut, trimmed and sized to your required lengths. Excess ends are removed to give standard dimensions and clean, smooth cuts for fast on-site installation.
Professional welding to splice, shape and reinforce steel structures. Finished components feature a stable overall structure and dense weld seams that meet the load-bearing and assembly requirements of engineering projects.
Full-range galvanizing including hot-dip galvanizing, electro-galvanizing and thermal immersion galvanizing, selected by application. The zinc layer isolates steel from air and moisture, greatly improving rust and corrosion resistance and extending service life.
A full range of specifications lets us deliver flexible, reliable material packages for complex builds. HZXY building materials have been used on the following projects.
Steel materials for long-span marine bridge construction.
HZXY profiles, plates and valves.
HZXY profiles, plates and valves.
HZXY profiles, plates and valves.
Steel materials for a landmark long-span structure.
Steel materials for a space-frame venue structure.
From production workshops to the freight yard, our facilities and logistics team keep material moving smoothly to global ports.
A transparent, five-stage workflow refined over 30 years of exporting, designed so procurement managers always know what happens next.
Send grade, standard, size, length, coating, quantity and destination port, or simply your project drawings and bill of materials.
We match stock or schedule production at our Tianjin and Tangshan bases and confirm tolerances and equivalent grades in writing.
Cutting, drilling, welding, bending, galvanizing or painting are completed in-house before packing.
Dimensional and surface checks with test reports. Third-party inspection agencies appointed by the buyer are welcome.
Steel-strapped bundles, waterproof coil wrapping and marking per your labels, loaded by container or break-bulk through Tianjin Port.
Tenders often specify ASTM, EN or JIS grades while Chinese mills certify to GB. This quick reference shows the equivalents our team uses when preparing order confirmations.
Note: under GB/T 1591-2018, the former grade Q345 was replaced by Q355, raising the minimum yield strength from 345 MPa to 355 MPa. Ask for Q355B when updating older specifications.
| China GB | ASTM (US) | EN (EU) | JIS (JP) | Min. Yield* | Typical Products |
|---|---|---|---|---|---|
| Q235B | A36 | S235JR | SS400 | 235 MPa | H-beam, angle, channel, flat bar |
| Q355B | A572 Gr.50 | S355JR | SM490 | 355 MPa | Heavy frames, bridges, plates |
| DX51D+Z | A653 CS | DX51D+Z | SGCC | Forming grade | Galvanized coil, roofing |
| SAE1008 | AISI 1008 | DC01 (approx.) | SWRM8 | Low carbon | Wire rod, nail wire |
