How It Works
GRATEFIX™ is a heavy-duty clamp that allows open floor grating to be clamped to the supporting steel from the top. Gratefix™ features a cast bottom piece that provides additional strength to clamp on to the steel flange. The Gratefix™ is available in different styles to suit various dimensions of the beam clip application. A mechanical galvanized M10 version is available with a symmetrical top bracket to suit 1-3/16” ctrs grating or with an offset bracket to suit 1-3/16” - 1-5/8” ctrs grating. The M08 version is also available in grade 304 and 316 stainless steel with a top bracket to suit 1-3/16” ctrs.
Option 1:
Pressed Top Bracket – Stainless Steel to EN 10088 Grade 1.4301 (AISI 304)
Cast Bottom Bracket – Stainless Steel to ASTM A743 Grade CF-8 (S30400)
Option 2:
Pressed Top Bracket – Stainless Steel to EN 10088 Grade 1.4401 (AISI 316)
Cast Bottom Bracket – Stainless Steel to ASTM A743 Grade CF-8M (S31600)
Option 3:
Pressed Top bracket – Material: Mild steel to EN 10025 grade S275
Cast Bottom Bracket – Material: Malleable iron to BS 1562: Grade EN GJMB-300-06
Both finished in: Mechanical Galvinized to ASTM B695
