Box Gabions Gabion Mattresses

Triple Life Coated Gabions:Gabions shall be manufactured from hard drawn welded wire, mesh size 76.2mm x76.2mm (available wire diameters 3.0mm, 4.0mm, 5.0mm). The wire shall be coated with Triple Life corrosion protection (95% Zinc 5% Aluminium) having a minimum coat weight of 240grams per square metre. The gabion units shall be supplied with appropriate lacing wire or helicals for assembly and erection.All wire to conform to BS1052.

PVC-Zinc Coated Gabions:Gabions shall be manufactured from hard drawn welded wire, mesh size 76.2mm x76.2mm with zinc and green PVC coatings (avaialable in wire diameters of3mm/3.50mm and 3.8/4.3mm), product name Masterplax.

Masterplax is produced to the following international standards;• Wire to BS1052• Zinc coating to BSEN10244-2:2001• PVC coating sustem, fusion bond method according to DIN3036 part 2, and ASTM-F 688-88 type class 2b. Class 2b PVC coated wire has the pVC coating fused and adhered to a primer that is cured on to the galvanized steel core wire. Minimum coating thickness is 0.25mm.

The mesh complies with BS2782 Part 5, using method 540B (ISO4892), as required bythe White Book 6.26/4 - August 1994.
