In today's era of rapid technological development and increasingly complex industrial systems, strength, corrosion resistance and durability have become the three indispensable core elements in the design of building structures and mechanical systems. Among the many optional materials, S280GD Galvanized Steel Pipe has become one of the preferred materials in the global construction and industrial manufacturing fields due to its excellent performance, wide application and economy.
S280GD galvanized steel pipe is a high-strength low-alloy structural pipe made by hot dip galvanizing technology, with a minimum yield strength of 280 MPa. The thickness of the zinc layer on its surface is usually between 60–275g/m², forming an excellent anti-corrosion barrier that can isolate the external oxidizing environment and has electrochemical protection function. Even if the zinc layer is partially damaged, it can continue to protect the substrate from corrosion.
The pipe complies with many international standards such as ISO, EN10219, EN10210, ASTM A53, JIS G3444, etc., and can be adapted to engineering projects and technical specifications worldwide.
Common production processes include:
ERW (resistance welding)
HFW (high frequency welding)
SAW (submerged arc welding)
SMLS (seamless pipe) (suitable for high pressure or high precision scenarios)
S280GD galvanized steel pipe has a yield strength of more than 280 MPa, which can provide stable support under various complex working conditions and is suitable for load-bearing structural occasions such as beams, columns, scaffolding, etc.
The zinc layer has long-term antioxidant ability and can effectively resist harsh environments such as humidity, acid rain, and sea breeze. It is very suitable for outdoor construction and marine engineering.
It is suitable for cutting, welding, tapping, bending and other processing processes. It is not easy to crack and is convenient for on-site installation and secondary processing.
The product has passed ISO9001, CE, SGS and other multiple certifications, with traceable quality and universal for global projects.
S280GD hot dip galvanized steel tube has shown strong practical value in many industries:
Building structure engineering: used for bridge supports, scaffolding, railings, fences, steel structure houses, etc., which is a common type of structural galvanized pipe.
HVAC system (HVAC): used for ventilation ducts, air conditioning pipes, smoke exhaust systems, with good sealing and rust resistance.
Agricultural machinery and equipment: suitable for sprinkler systems, greenhouse frames, farm fences, etc., with strong soil corrosion resistance.
Oil and gas industry: used for low-pressure oil pipelines, gas transmission brackets, etc., as a reliable ASTM galvanized pipe choice.
Marine engineering: dock structures, shipyard facilities, coastal railings, etc. all require zinc-coated steel pipe.
Transportation facilities: guardrail pipes, bridge crash barriers, vehicle chassis pipes and other projects that require durability and impact resistance.
