Triple-S wall brackets made of GALVALUME coated 1.5 mm steel. (GALVALUME consists of 55% aluminum,
43,4 % zinc and 1,6 % silicium, Long-term evaluations show that 55% Al-Zn sheets will have a life of >30 to 40+ years, except in severe marine applications, and at least twice the life of galvanized steels) Carried out a test calculation of Bygningsinstitutteti in Iceland. With this test may be the distance between Wall Brackets and their carrying capacity determined.

Result:
fracture load approx.  8.00 kN 
Visual deformation of 3.50 kN.
R d = 2.60 kN.
