Orrcon Steel distributes and manufactures rectangular hollow sections ranging from 38x25mm to 400x300mm.* Our Rectangular Hollow Sections are manufactured to the Australian Standard for structural steel hollow section AS/NZS 1163 and cover steel grades C250L0 and C350L0.

A variety of surface finishes are available across our range of structural tubulars, but not all finishes are available in all sizes.

Sizes outside this range are available (subject to enquiry).
