Distributor Coil Galvalume - Jakarta, Indonesia

The combination of zinc and aluminum in Galvalume enhances both the positive and negative effects of aluminum.  Galvalume has barrier corrosion resistance and heat resistance similar to aluminized material and good bare edge galvanic protection and forming qualities like galvanized material. Consequently, Galvalume  and Galvalume Plus will resist rust, the elements and fire while providing a sturdy and protective covering.

Galvalume® is more corrosion-resistant than galvanized steel, but because aluminum provides barrier protection instead of galvanic protection, scratches and cut edges are less protected.  Galvalume is offered in both bare and pre-coated versions. Most Galvalume®–like galvanized steel– is coated. But Galvalume has an excellent performance life in bare exposures as well.  Both galvanized steel and Galvalume® weigh 100 to 150 pounds per 100 square feet and contain about 35% recycled materials. The cost of Galvalume and Galvalume Plus are about the same as that of galvanized steel.The coating used on  Galvalume is very important because it is critical to the length and conditions of the entire warranty of the panel product. Coated metal roof panels have progressed from a single coat straight polyester paint system in the early years to Poly vinyl idene fluoride(PVDF)  acknowledged as the premium resin for coil coatings.  It is a kind of fluoride, a family that includes such well known products as Teflon and Halar.  PVDF resin has superior chalk resistance and gloss retention as well as stain and chemical resistance.  It is softer than polyester, making it highly formable without risk of cracking. Current pretreatments and primers along with superior paint coating have increased product warranties dramatically.

Lip channels are predominantly used as a structural component when erecting or constructing buildings and structures. This has also lead to lip channels quite often being referred to as purlins. Though this may be the main use, cold formed steel lip channels are used for other industries such as racking and shelving, trailer manufacturing and many more make use of lipped channels.

Lip channels are cold formed from a number of different steel types. The most popular steel types used in the roll forming of lipped sections include: Hot Rolled Mild Steel, Z275 Pre-Galvanized Steel and 3CR12 Stainless Steel.

A truss is a structure that "consists of two-force members only, where the members are organized so that the assemblage as a whole behaves as a single object. A "two-force member" is a structural component where force is applied to only two points.

Although this rigorous definition allows the members to have any shape connected in any stable configuration, trusses typically comprise five or more triangular units constructed with straight members whose ends are connected at joints referred to as nodes.

In this typical context, external forces and reactions to those forces are considered to act only at the nodes and result in forces in the members that are either tensile or compressive. For straight members, moments are explicitly excluded because, and only because, all the joints in a truss are treated as revolutes, as is necessary for the links to be two-force members.
