Ruspert metal finish is a high-grade, non-organic, tri-layered ceramic surface coating developed to attain optimum perfor-mance in the various pollutive and atmospheric conditions that cause corrosion. It consists of three layers:

  • The 1st layer: a metallic zinc layer.
  • The 2nd layer: a high-grade anti-corrosion chemical conversion film
  • The 3rd top layer : a baked ceramic top coating.

The unique feature of Ruspert Coating is the tight joining of the baked ceramic top coating and the chemical conversion film thanks to the cross-linking effect. These layers are bonded together with the metallic zinc layer through chemical reactions, and this unique method of combining layers results in a rigid and dense combination of the coating films.

Ruspert Coating treatment does not attribute its anti-corrosion properties to merely a single material, but the synergy of these three layers, which combined have superb rustproof qualities. Compatible with metal coated and painted surfaces, fasteners coated with Ruspert are resistant to acid and alkaline attack, galvanic corrosion and hydrogen embrittlement.




Ruspert Coating Processes


  • Material : metallic zinc & resin
  • Coating Type : metallic zinc (3 layers) dip-coating baked ceramic top coating
  • Minimun Average Coating Thickness : 20µ、 30µ、 40µ
  • Salt-spray Test : 500、1000、1500 hrs

Extra-heavy plating provides long corrosion-free service.

EPDM Sealing

Made of macromolecule material, the EPDM seal contains excellent characters of aging, unltraviolet rays resistance and endure to ozone, high temperature and low temperature (-50°C - 150°C).


Hi-grip

Hi-grip is a dual-threaded system that provides positive support to roofing profiles and secures a watertight seal between fastener and roofing sheet during crest fixing.


Drillshield

To enlarge the hole in the profile, and to avoid damage to the protective coating on the shank beneath the roof.


Thread

PATTA fasteners are designed to give the best possible holding power with a low installation torque. As thinner high tensile sections are introduced our engineers ensure that stallation torque. As thinner high tensile sections are introduced, our engineers ensure that screws have optimum holding power and pullout Strength.

Hi Teks

C-1022 steel case hardened drill point that will drill and thread in structural steel and mild steel. this technology designed in a manner much the same as a high speed drill bits.

Need help in choosing the right self drilling screws ???
