Light-Gauge Steel Pipes
Light-gauge steel pipes are a reduced-wall ERW range for projects in the Philippines. Check that your approved design permits the published wall thickness before choosing a size or finish.

- Electric Resistance Welding (ERW)
- Material options
- Black Iron (BI) and Galvanized Iron (GI)
Applications
Start with the approved wall and service requirement. A lighter pipe is not an automatic substitute for a heavier product.
What is light-gauge steel pipe?
Light-gauge steel pipe is Supreme's reduced-wall ERW pipe range for projects where the approved design does not require a heavier wall. The published range includes black iron and galvanized iron finishes.
Match the standard and dimensions to the approved design before choosing a lighter wall. For plumbing, also check pressure, joints, installation and code requirements.
TRI-R is Supreme’s light-gauge ERW pipe brand.
For a wall-thickness comparison, read how heavy and light gauge pipe differ.
Choose black or galvanized finish.
Finish is separate from wall thickness. Choose it from the project exposure, coating requirements, fabrication method, and maintenance plan.
Compare black and galvanized pipe when choosing the finish.
Compare light-gauge pipe sizes and standards.
Use a lighter wall only when the project permits it. Match the nominal size, outside diameter, wall thickness, and mass in one published table row.

Review the light-gauge pipe specification.
Use a lighter wall only when the design and governing standard permit it. It is not an automatic substitute for a heavy-gauge pipe with the same nominal size.
