| High Light | Q235 Carbon Structural Steel Welded Steel Pipe ，Architectural Application Carbon Steel Square Pipe ，Cold Drawn and Hot Rolled Structural Steel Tube | ||
Q235 is a mild (low-carbon) structural steel widely specified in China under GB/T 700. It is commonly produced into welded square hollow sections (SHS) for building and architectural steelwork because it balances strength, weldability, formability, and cost efficiency.
Typical supply options for carbon steel welded square pipe (SHS):
Manufacturing: ERW (Electric Resistance Welded), cold-formed from strip/coil
Outside size (OD across flats): customizable (common ranges: ~20×20 mm up to ~400×400 mm)
Wall thickness: customizable (common ranges: ~1.0 mm up to ~16.0 mm)
Length: 6 m / 12 m standard; cut-to-length available
Ends: plain / deburred; end caps optional
Surface: black (mill finish), oiled, painted/primed, hot-dip galvanized (for corrosion resistance)
Inspection / documentation: dimensional checks, weld seam inspection, and MTC/COC available upon request
Clean square geometry for architectural frames, handrails, façade substructures, and general structural fabrication
Reliable welding performance suitable for common fabrication methods (MIG/MAG, SMAW, etc.)
Good strength-to-cost ratio for non-critical to medium structural loading
Easy finishing: paint, powder coat, or galvanizing for outdoor use
Architectural fabrication is sensitive to outside dimensions, wall thickness, straightness, squareness, corner radius, and twist. We can supply to recognized hollow-section tolerance practices and provide measurement records when required.
Many projects require compliance to a regional hollow-section standard (e.g., ASTM A500 or EN 10219) with traceable marking and documentation. We support standard-based production routing and documentation packages (MTC/COC, heat/coil traceability, marking rules) to match project submittal requirements.
Outdoor architectural steelwork often fails early due to coating mismatch. We offer surface preparation + coating options (black/oiled, primer/paint-ready, galvanized) aligned to the intended exposure class and finishing workflow, minimizing rework on-site.

| St3sp | ≥205 | 370–480 | ≥23 |
ASTM: ASTM A500 (structural tubing / HSS for square & rectangular), often paired with project requirements for tolerances and testing
EN: EN 10219 (cold-formed welded structural hollow sections; Part 1 delivery conditions, Part 2 tolerances/dimensions)
GOST: GOST 380 (ordinary quality carbon steel grades such as St3sp)
JIS: JIS G 3101 (SS400 structural steel for general structure)
GB: GB/T 700 (Q235 grade family); commonly used with GB hollow-section product standards for welded SHS in construction
Main application fields: architectural structures, building frames, façade support systems, public-space steelwork, and general fabrication.
Where it is used in architecture (examples):
Structural frames: secondary steel frames, bracing members, portals (as design allows)
Architectural metalwork: canopies, sunshades, screens, pergolas
Public facilities: railings, fences, bollard frames, equipment supports
Fit-out steel: partition framing, signage structures, display frames
A: manufacturer,also can do trading.
A: Generally speaking,it is 10-15 days if the goods are in stock,or it is 30-40 days if the goods are not in stock,
it is according to quantity.
A: Yes, we could offer the sample for free charge but need pay the cost of freight.
A: Payment<=2000USD, 100% in advance. Payment>=2000USD, 30% T/T in advance ,balance before shippment.
