Climaseal® 4 should be used in coastal areas where salt, wind, UV and moisture are prevalent, in tropical zones and industrial areas. It is particularly recommended for use in moderate and severe marine environments.
Technical Data and Documents
Buildex® Roofing & Cladding Screws
Buildex® Metal Teks Hexagonal Head screws are designed for fixing 2.5mm to 6mm roofing & cladding profiles to steel purlins. The Self-Drilling Screws come with a hardened drill point that will drill and thread in structural steel and mild steel. These Teks points are designed in a manner much the same as high speed steel drill bits.
Climaseal® 4, the latest coating finish from Buildex, is the end-result of over ten years of “real world” testing, providing a thorough understanding of corrosion and its prevention:
Real world testing has exposed many deficiencies with the acceptance of coated finishes as “deem to comply”, simply because of thickness and density measurements.
The new Climaseal® 4 coating is a layered system, combining both high density sacrificial coating substrate, over which a barrier top coat has been applied.
The Climaseal® 4 is then applied by a new environmentally friendly, processing system. Climaseal® 4 meets and exceeds AS3566 Class 4 specifications.
To choose the correct fastener, it is necessary to select one where the length of the drill point is equal to or greater than the total thickness of the material to be drilled including the air-gap. If the drill point is less than the total thickness of the material and the thread engages, then the fastener can break or became impossible to drive.
