Product overview

What is this steel pipe or tube product?

This product is a hot-dip galvanized square hollow section, or SHS, with Q235 and Q355 material references. Equal-sided square geometry distinguishes it from the rectangular hollow section, round welded tube and spiral-welded pipe products in the same collection. Buyers should identify the exact SHS outside dimension, wall thickness and finished length for every required section. The native title contains dimension examples that do not consistently describe a square section, so the quotation should rely on the confirmed drawing and section schedule rather than those examples. State the required material designation and galvanized coating specification, together with tolerances, end details and any holes shown on the fabrication drawing. The section name alone does not establish the capacity of the completed structure. Quantities by size, packing instructions and destination complete the RFQ for the required galvanized SHS material.

FAQ

Product Questions

Is this product a square or rectangular hollow section?

Owner has confirmed this product as a square hollow section (SHS). Submit equal outside dimensions and wall thickness from the project drawing.

Should the dimension examples in the native title be used for ordering?

What is needed for a galvanized SHS quotation?

Send outside size, wall thickness, lengths, Q235 or Q355 requirement, coating specification, drawings, quantities and destination.
