ASTM A36 Hot Rolled ERW Hot Dipped Galvanized Steel Plate for Construction
This ASTM A36 hot rolled ERW hot dipped galvanized steel plate is a high-performance structural material independently developed and produced by YTDR Group, dedicated to high-rise building load-bearing structures, industrial workshop frames, highway guardrail foundations, prefabricated building components, and municipal infrastructure projects. It is tailored for B-end customers including engineering contractors, construction material distributors, prefabricated building manufacturers, and infrastructure procurement companies, providing standardized and customizable solutions to meet the material needs of large-scale, long-service-life construction projects.
Data & Test Results to Solve Industry Pain Points
● Superior corrosion resistance：The hot dipped galvanized coating with thickness ≥80g/㎡ forms a dense zinc-iron alloy layer, which can achieve 15–20 years of anti-rust service life in outdoor atmospheric environments, and 8–10 years in coastal high-salt fog areas. Compared with ordinary spray-painted steel plates, the corrosion resistance is increased by 300%, effectively solving the pain point of frequent maintenance of outdoor steel structures.
● High strength & structural stability：ASTM A36 base material yield strength ≥250MPa, tensile strength 400–550MPa; ERW welding process ensures weld strength ≥ parent material strength, with no welding cracks or porosity detected by ultrasonic flaw detection. The flatness error is ≤±1.2mm/m, avoiding structural deformation caused by uneven stress in large-span buildings.
● Excellent processability & compatibility：The hot-rolled base material has low carbon equivalent (≤0.38%), supporting all common welding methods (arc welding, gas shielded welding, resistance welding) and on-site processing (cutting, drilling, bending). The galvanized layer does not fall off during processing, solving the problem of secondary corrosion at processing ports.
For customers with personalized project needs, YTDR Group provides one-stop customized services, no minimum order quantity (MOQ) limit for bulk orders:
● Specification customization：Non-standard thickness (200mm–300mm), ultra-wide (3000mm–4000mm) and ultra-long (18000mm–24000mm) steel plates can be customized according to construction drawings; ERW welding seam position and width can be adjusted according to structural design requirements.
● Surface treatment customization：High-thickness galvanizing (180–275g/㎡) for severe corrosion environments, passivation treatment to prevent white rust during storage, anti-fingerprint coating for decorative applications; shot blasting + epoxy primer for direct on-site installation.
● Packaging customization：Export standard seaworthy packaging (waterproof film + wooden pallets + steel banding) for long-distance sea transportation; vacuum packaging for small-batch precision components; customized packaging marking according to customer requirements (project name, specification, batch number).
YTDR Group’s ASTM A36 hot rolled ERW hot dipped galvanized steel plate has passed a number of international authoritative certifications, ensuring compliance with global construction project material standards and reducing trade risks for customers:
● Mandatory quality & safety certifications：ISO 9001 quality management system certification, CE certification (compliant with EU Construction Products Regulation CPR), SGS/BV third-party inspection report (including chemical composition analysis, mechanical property test, zinc coating thickness test, salt spray corrosion test).
● Industry special certifications：API 5L certification, applicable to steel plates used in building supporting oil and gas pipeline auxiliary structures, expanding the product application scenarios.
● Trade support certificates：Original manufacturer certificate, CO (Certificate of Origin), FORM A/FORM E (preferential tariff certificate), which helps customers reduce import tariffs by 5%–15% and speed up customs clearance by 3–5 working days.
Supply Chain Capabilities
● Production capacity：Equipped with 4 advanced hot rolling production lines, 2 ERW precision welding lines, and 1 full-automatic hot dipped galvanizing production line, with an annual production capacity of 50,000 tons. The lead time for standard size steel plates is 5–10 days; for bulk customized orders, the delivery time can be negotiated according to the project schedule to ensure on-time delivery.
● Logistics service：Support FOB/CIF/EXW/DDP delivery terms, long-term strategic partnership with top shipping lines (Maersk, CMA CGM, COSCO). Provide real-time logistics tracking service, and door-to-door delivery for global customers, covering more than 80 countries and regions.
● Quality inspection：Implement 100% full inspection before shipment — including dimensional measurement, surface quality inspection, zinc coating thickness test, ultrasonic flaw detection, and mechanical property sampling test. Third-party inspection (SGS/BV) can be arranged at the buyer’s designated location, with a 18-month quality warranty for all products (longer than the industry average of 12 months).
