Ontrend Industrial Ltd. supplies ERW steel tubes in carbon steel grades Q195, Q215, Q235, and Q345, manufactured to multiple international standards including ASTM A53, EN 10219, and JIS G3444. The tubes are available in round, square, rectangular, oval, and elliptical profiles, with outer diameters ranging from 10mm to 400mm and wall thicknesses from 0.8mm to 12mm. Surface finishes include black, bright, galvanized, painted, and powder-coated variants.
The material is cold-rolled carbon steel strip, welded using electric resistance methods to ensure consistent seam integrity. Standard tolerances follow GB/T 13793-2008 for round tubes and EN 10219 for structural hollow sections. Galvanized and powder-coated options are applied post-weld, with zinc coating typically ranging from 40g/m² to 80g/m². These tubes are not seamless and are not intended for high-pressure fluid systems without additional certification.
These tubes serve construction, furniture, fitness equipment, and light mechanical frames. Buyers include machinery assemblers in Australia, retail distributors in Europe, and infrastructure contractors in Southeast Asia. Packaging is in steel-banded bundles, with options for oiling or PVC wrapping. MOQ is typically 1 ton, and lead time is 15-25 days after order confirmation. All trade terms must be confirmed directly with the supplier.

Verify the exact grade (Q195 to Q345), profile shape, and surface finish before ordering. Request a mill test certificate that includes chemical composition and mechanical properties for each batch. Confirm whether galvanized or powder-coated tubes meet ASTM A123 or ISO 1461 for coating adhesion. Do not assume all listed standards are met unless explicitly confirmed in writing.
Lead time is typically 15-25 days from order confirmation. Shipping is usually FOB Shanghai or Ningbo, with CNF or CIF available. Payment terms are commonly 30% advance, 70% against shipping documents. Incoterms must be clearly defined, especially regarding insurance and unloading responsibilities. Packaging options include steel belts, oiling, and waterproof plastic - specify your preference to avoid damage in transit.
Upon receipt, inspect for coating uniformity, weld seam integrity, and dimensional accuracy using calipers and a magnetic thickness gauge. For galvanized tubes, check for white rust or bare spots. Retain samples and document any discrepancies with photos. For structural use, consider third-party inspection by SGS or Bureau Veritas to validate compliance with the specified standard, especially if used in public infrastructure.
