Galvanized rectangular tube in a welded light-fabrication direction for railings, handrails, balcony frames, doors and light gates. Review 20×10–100×50 mm sections, 1.0–3.0 mm wall options and a 6 m reference length. Confirm grade, coating and tolerance per order.
This welded galvanized rectangular tube is intended for railings, handrails, balcony frames, door frames and other light fabrication. A working direction of 20×10–100×50 mm outside size, 1.0–3.0 mm wall thickness and 6 m reference length can be reviewed. Confirm the final section, grade, coating, tolerance and length per order.
The rectangular section offers a defined wide face for railing panels, frame connections and light fabricated assemblies. This tube is welded, not seamless, and should be matched to the project’s load, span, joint and finishing requirements. It is not presented as a heavy structural engineering product. The wider face can also help with brackets and visible frame members. The section is easy to identify in a mixed fabrication order.
Q195 and Q235B are suggested grade directions for general fabrication. The buyer should choose one grade and governing standard, then confirm zinc coating, corner radius, straightness and surface requirements before production. Keep the selected section and grade consistent across the drawing and purchase order. Confirm the visible face before production.

This light rectangular-tube direction can be reviewed for railings and general fabrication where a defined wide face helps with joints or visible frame members. The rectangular tube suits small frames that need a broader face for fixing or panel support. Railing and light-fabrication buyers can review the section against their own drawings. It is not a heavy structural section; confirm load, span and connection details before selection.
Confirm cutting, drilling, welding, punching and end preparation against the drawing. State the exposed face and visible-surface requirement where appearance matters. Confirm corner radius, straightness and dimensional tolerance before production. State whether the tube will be mechanically joined or welded after delivery. Record the approved section and cutting tolerance on the order. Confirm the joint detail before cutting and mark the visible face.
Confirm bundle quantity, length, strapping, moisture protection, marking and loading requirements per order. Protect the finished galvanized surface from rubbing, impact and prolonged wet storage. Identify mixed sections clearly during loading. Protect open ends and visible faces during handling. Keep mixed sizes clearly separated.
No. This rectangular tube is welded galvanized steel for light fabrication and frame work.
No heavy structural claim is made. Confirm the project design and load before use.
The working direction is 20×10–100×50 mm. Confirm the exact dimensions and tolerance per order.
Q195 or Q235B may be reviewed for general fabrication. Confirm one grade and standard in the order.
State the exposed face, surface appearance and finishing requirement before production review.
Send outside size, thickness, grade, coating, length, quantity, finish, tolerance and packing requirements.
