Building & Structural Work
Well‑suited for main frames, support members and bracing systems in general‑purpose construction projects.
Metal Fabrication
Perfect for machinery frameworks, equipment bases and custom‑welded steel assemblies.
Industrial‑Site Applications
Commonly used for work platforms, access walkways, pipe supports, conveyor frames and warehouse storage structures.
Infrastructure Projects
Fits bridge parts, safety guardrails and a wide range of public‑utility steel structures.
General‑Engineering Fabrication
Great for brackets, mounting frames, jigs and custom metal components for on‑site repair and maintenance jobs.
1) Branch Office - Spanish-speaking support, customs clearance assistance, etc.
2) Over 5,000 tons of stock in stock, with a wide variety of sizes
3) Inspected by authoritative organizations such as CCIC, SGS, BV, and TUV, with standard seaworthy packaging
Base Moisture‑Proof Protection
Every bundle gets wrapped in tarpaulin. Two to three desiccant sachets are placed inside each package, then the whole unit is sealed with heat‑bonded waterproof fabric.
Strapping & Bundle Weight
Heavy‑duty steel straps (12‑16 mm diameter) secure each load. We keep individual bundle weights between 2‑3 tons to match lifting‑equipment limits at U.S. ports.
Custom Bundle Marking
Dual‑language labels (English / Spanish) are affixed on every shipment. Labels clearly display material grade, product specifications, HS code, batch number and mill‑report reference number.
Stable cooperation with shipping companies such as MSK, MSC, COSCO efficiently logistics service chain, logistics service chain are we to your satisfaction.
We follow the standards of quality management system ISO9001 in all procedure, and have strict control from packaging material purchase to transport vehicle scheduling.
1. What size options do you carry for ASTM A36 angle bars?
Our regular stock covers sizes from 20×20 mm up to 200×200 mm, with wall thickness ranging 3‑20 mm. Non‑standard dimensions can also be made to order.
2. Can ASTM A36 angle iron be welded?
Definitely. This grade delivers great weld‑ready performance with common welding techniques, including MIG, TIG and stick arc welding.
3. May I use A36 angle bars for outdoor‑exposed projects?
It works for outdoor use, though extra surface protection like paint, hot‑dip galvanizing or anti‑rust coating is strongly recommended.
4. Are galvanized A36 angle bars available?
Yes. We can hot‑dip‑galvanize or apply zinc coatings on A36 angles to boost corrosion resistance.
5. Can A36 angle bars be processed to custom‑fit dimensions?
We offer a full range of fabrication services: length cutting, hole‑drilling, punching and custom manufacturing following your technical drawings.
6. What are the default stock lengths for A36 angle bars?
6‑meter and 12‑meter lengths are our standard options. Other cut‑to‑order lengths such as 8 m or 10 m are also acceptable.
7. Are Mill Test Certificates provided with shipments?
Yes, MTC documents compliant with EN 10204 3.1 will be issued, or we can adjust certification content to meet your specific demands.
