Coating Technology

Research done on causes of steel building failures showed that about 80% of these failures start from the fasteners. Because fasteners constitute only approximately 8% of the entire project cost, several builders have the tendency to neglect this vital aspect of their project. Their excuse being cost cutting, lack of knowledge or not important to them. This is especially disheartening when we hear it from a professional.

We want to provide a fastener that is able to last 4 or 5 times longer but at a fraction of the cost. That is why we applied Coating to our fasteners. It doesn't cost as much as stainless steel fasteners and perform much better than electro zinc plated fasteners. We all know that the basic function of a Self-Drilling Fastener is to self-drill in one operation and to fasten onto outdoor structures without giving corrosion or embrittlement problems. We have come up with a solution specifically for these functions and we have done it exceptionally well with Self-Drilling Fasteners.

as the name itself states provides superior protection against corrosion and is especially suitable for outdoor projects. With coating, Self-Drilling Fasteners now come not only with excellent corrosion protection, it drastically reduces the risks of hydrogen embrittlement problems . We have that much confidence with our products that we are not only going to just lay claims. We tag all Self-Drilling Fasteners with our own warranty against pre-mature corrosion.

What is ?
As the name itself implies, it is a fastening system that is shielded from corrosion problems. fasteners are coated with our in-house proprietary coating. The coating technology was initially imported from Australia and further innovated by our engineers to better suit our application. Basic compound of coating consist of Tin-Zinc and is mechanically deposited.

What is AS 3566 - 1990 (Class 3)
The AS 3566 is a standard established by the Standards Association of Australia to specify the requirements for a self-drilling screw to be suitable for use in steel and timber. It clearly specifies certain criteria that a suitable fastener should meet. One of the most important criteria of this standard covers the corrosion resistant requirements of a self-drilling screw that will be suitable for use in steel and timber. This corrosion resistant criterion has been used by several major manufacturers and contractors of metal roofs and steel building structures as the minimum standard for any self-drilling screw manufacturer to achieve in order for their fasteners to be fit for use with their steel structural products.

Test Reports
Tests are conducted in accordance with the testing criteria as stipulated by Standards of Australia under 3566 Class 3.
