Our tubes fall into 2 distinct categories, namely: Mechanical & Structural.

• The mechanical is made from SAE 1008 coil and covers the 1.6, 2.0 & 2.5mm wall thickness range.
• 3.0, 3.5, 4.0, 4.5 & 6.0mm material is more often manufactured in grade S355 coil for construction industry conformance.
• 3.0mm is also available in SAE 1008 material, so quality clarity is important when ordering.
