When choosing a supplier, quality materials are a top priority. That’s why SCAFCO steel framing products are manufactured from 100% prime mill certified steel. SCAFCO’s products exceed industry standards as they are manufactured from 57 ksi steel in place of 50 ksi and G90 in place of G60 for 68 mil and heavier.
