ALLGAL® steel hollow sections offer fabricators, builders and manufacturers so many benefits that it is now one of the leading Zinc coated tubulars available on the Australian market today. Whether it's for a shade structure, cattle yard, bus shelter, floor framing or fence post, ALLGAL is now specified and used in a myriad of applications across Australia and New Zealand.
ALLGAL®combines the strength and durability of structural steel with the corrosive protection properties of Orrcon Steel's unique duplex coating system. This coating system comprises a uniform and consistent electro-galvanized zinc coating and Clear-Tec clear polymer protective coating. Because ALLGAL® is manufactured with high purity zinc on both sides prior to being cold-formed into hollow section, all ALLGAL products are protected from corrosion on the inside and out.
ALLGAL® is an excellent alternative to other in-line galvanized and hot-dip galvanized steel sections.
Orrcon Steel’s ALLGAL steel hollow sections are manufactured to comply with the mechanical property requirements of: AS/NZS 1163 Cold-Formed Structural Steel Hollow Sections in grades C250 L0, C350 L0, C450 L0 and the minimum properties of AS 1074 Steel Tubes and Tubulars for Ordinary Service.
