A500 GRA GI Pipe Hot Dipped Round Sqaure Steel Tube Tubos
Products Description
ASTM A500 Gr.A is cold-formed welded and seamless carbon steel structural tubing inround, square, and rectangular shapes. The designation Grade A refers to a specific strength grade within this common family of structural steel shapes.
Grade
Gr.A orB, C.Grade Ais a general-purpose grademoderate strength.
Forming Process:The tubes arecold-formedfrom sheet or strip steel, which generally results in higher strength and better surface finish compared to hot-formed sections.
Typical Chemical Composition & Mechanical Properties (for Round Tubing):
Carbon (C) | 0.26% max |
Manganese (Mn) | 0.30-1.35 per cent |
Yield Strength | Min 228 Mpa |
Tensile Strength | Min 310Mpa |
Elongation | Minimum of 25% (indicating good ductility). |
Shape Variety & Key Advantage:
Available inRound, Square, and Rectangularhollow structural sections (HSS).
Applications:
Building Construction:Columns, beams, trusses, and purlins in commercial and industrial buildings.
Bridge componentsandhighway sign supports.
Space frames, guardrails, and architectural frameworks.
Transmission towers, lighting poles, and crane booms.
Important Distinction:
It is crucial to differentiate ASTM A500 (structural tubing) from standards likeASTM A53(pipe for fluid transport) orASTM A106(pipe for high-temperature service). A500 is designed for carryingstructural loads, not for conveying fluids under pressure, though it is sometimes used for non-critical fluid applications.
