Technical information

Information on the most common standards, supply status of rectangular, square and round tubes. Round tubes – drawn, straightness, tolerance.

most common norms

NBR 8261 | NBR 6591
DIN EN 10.305-3 (former DIN 2394)
ASTM A 500

Upon request, we can meet other standards.

Application

The tubes are intended for the civil construction, agricultural machinery, automotive industry, furniture industry, fitness segment markets, among others. Generally used for structural purposes.
Considering the wide application, it is recommended to quote the application of the material when placing the purchase order.

Thickness

The tubes are generally produced with the thickness and tolerances of the steel mills, however, for the purpose of guaranteeing the tubes, we adopt a ± 10% tolerance in relation to the nominal size. Special tolerances can be adopted upon request.

Straightness

The maximum deviation from straightness must be 2.5mm per meter of tube length.
T01 – Length
Tubes can be supplied with fixed lengths, with up to 5% of short tubes coming from the manufacturing process with the following tolerances:
Manufacturing length (mm) Tolerance
From 4000 to 8000 +20 -0
From 8001 to 12,500* + 50 -0

*Length on request
