WIRE MESH GABIONS QUALITY - in compliance with ASTM A975 for double twisted wire mesh gabions

Supplied with geotextile and filter fabrics, help with assembling, filling and tying open wire mesh rectangular gabions, baskets and cages.

Gabions are manufactured in variable sizes, uniformly partitioned into internal cells, interconnected with other similar units, and filled with stone at the project site to form flexible, permeable, monolithic structures. Gabions are manufactured with all components mechanically connected with the exception of the mattress lid, which is produced separately from the base.

All gabions wire materials are in compliance with ASTM A975 for double twisted wire mesh gabions.

PRODUCTS MATERIALS

Double twisted wire mesh Gabions

Double twisted wire mesh gabions are manufactured with a non-raveling mesh made by twisting continuous pairs of wires through three half turns (also known as double twisted) to form a hexagonal-shaped opening. Gabion sizes, wire diameters, mesh opening sizes, and tolerances shall comply with the requirements of ASTM A975:

Characteristics	Dimensions and Wire Diameters
Mesh Type	8 by 10
Mesh Opening	3.25 inches by 4.5 inches
Mesh Wire	0.120 inch
Selvedge Wire	0.150 inch
Lacing Wire	0.087 inch
Fasteners	0.118 inch
Stiffeners:
Using Lacing Wire	0.087 inch
Preformed	0.150 inch
*All dimensions and wire diameters are minimum nominal values

Gabions Hot Dip Zinc Coating shall meet the following test requirements:

(1) Metallic Coating: The coating weights shall conform to the requirements of ASTM A641, Class 3 (Style 1).

(2) Wire Tensile Strength: The tensile strength of the wire used for the double twisted mesh, lacing wire, and stiffener, when tested in accordance with Test Methods and definitions ASTM A370, shall be in accordance with the requirements of ASTM A641 (Style 1)

(3) Mesh Strength and Panel to Panel Joint Strength: The minimum strength requirements of the mesh, selvedge wire to mesh connection, panel to panel connection, and punch test, when tested in accordance with ASTM A975 Section 13.1. The strength values reported in lb/ft are referred to the unitary width of the specimen. The panel to panel test shall demonstrate the ability of the fastening system to achieve the required strength, and indicate the number of wire revolutions for the lacing wire or the ring spacing for ring fasteners used. The same number of wire revolutions or ring spacing shall be used in the field installation. Pleating the based panel to obtain internal panels is prohibited.

(Minimum Strength Requirements of Mesh and Connections)
Test Description	Gabions, metallic coated
Tensile strength parallel to twist	3500 lb/ft
Tensile strength perpendicular to twist	1800 lb/ft
Connection to selvedges	1400 lb/ft
Panel to panel (using lacing wire or ring fasteners)	1400 lb/ft
Punch Test	6000 lb

Wire Fasteners for Gabions

Fastening systems are recommended for woven wire gabions, according to ASTM A975, are steel ring fasteners for metallic coated gabions. For each shipment of wire gabions delivered, duplicate test reports or records are provided, for having been performed during the last year on all material contained within the shipment meets the composition, physical, and manufacturing requirements stated in this specification.

Ring fasteners for woven wire gabions:
Test results meet the requirements of the specifications, according to the following criteria:

• (1) That the fastener system can consistently produce a panel to panel joint strength as indicated for double twisted wire mesh gabions;
• (2) That the fastener system does not cause damage to the protective coating on the wire.

Samples of wire fasteners with certified test records shall be submitted at least 60 days in advance for approval.
