Strata Mesh, Strap and W-Strap are used in conjunction with friction stabilisers and other rock bolts to provide additional coverage in ground conditions where bolts and support plate cover is not sufficient. The ability to overlap the products enables continuous coverage of the rock surface.

Fero Strata Mesh is manufactured in house at our Perth and Brisbane manufacturing facilities using the latest in electric resistance welding technology. This enables Fero to manufacture Strata Mesh up to 6 metres in length and 2.4 metres wide, and to customise product in a range of configurations to assist in optimising bolting patterns. The mesh is manufactured with minimal overhang of line and cross wires to eliminate material handling injuries on site.

Strata Strap is used in conjunction with friction stabilisers and rock bolts to provide additional ground support by increasing the area of support provided and conforming to major irregularities in the rock. Fero’s strata strap range includes W-Strap and Strata Mesh Strap, which was developed as an alterantive to conventional W-Strap whereby the wire construction allows for simpler hole alignment. Strata Mesh Strap can also be supplied with an arch for use in shotcreting of pillars.

To ensure a consistently high quality product, Strata Mesh is weld-shear tested in-house every 300 sheets and torque tested every 50 sheets.

Strata Mesh and strap are available in untreated steel, pre-galvanised or hot-dip galvanised.

1.2 Strata Mesh Range

1.3 Strata Strap Range

Fero Strata manufactures and supplies a variety of Strata Mesh products appropriate for a range of ground conditions. Strata Mesh is available in a range of wire diameter and crosswire apertures and can be custom produced to suit specific site requirements.

Strata Mesh can be manufactured and supplied as pre-treated galvanised product to assist in the protection of the mesh in corrosive environments. Black Strata Mesh, also known as ‘Bright’ is a more cost effective product, however it does not offer the same level of protection in corrosive environments. With an additional anti-corrosive aluminium coating, Innogal mesh provides a higher level of protection in highly corrosive environments.

Contact the Fero Strata Team for further details.

Strata Mesh & Strap Strata Mesh is primarily used in conjunction with rock bolts when additional support is required in underground mining and tunnelling. The mesh straps are pulled into the rock surface by rock bolts and conform to irregularities in the rock. Ranging from 4-8mm diameter linewire and crosswire with standard 100 x 100 apertures, Strata Mesh can be customised to suit specific mine site requirements. The wire construction method of the strap allows greater flexibility in hole alignment and fit to the irregularities with the rock surface. Can be supplied in bright wire, galvanised or hot dip galvanised coatings

W-Strap Fero W-Strap is rolled from 1.9mm steel coil and shaped to form a ‘W’ with multi-holes spaced 300mm apart. The W shape of the strap grips the rock surface and increases the area of support when used in conjunction with rock bolts. W-Strap is supplied in standard lengths of 2.4m, 3m and 6m with other lengths available on request and can be supplied in un-treated pre-galvanised or Hot Dip Galvanised coatings.

Chain Link Mesh Chain link mesh offers an economical and durable solution for underground surface support. Fero offers chain link mesh in a standard galvanised finish in a variety of continuous roll size configurations to suit specific mine requirements. Standard widths include 1.8 and 2.4m and standard length rolls 10m, 15m and 20m.

The ground support mesh manufactured and supplied by Fero Strata for both domestic and international mining markets is manufactured under strict controlled conditions to meet the stringent requirements of mining ground support applications.

The ground support mesh manufactured at Fero is subjected to rigorous in-house testings (refer to table below). These tests are conducted at our Western Australian based Laboratory located at our Kewdale facility as well as periodic testing at NATA accredited laboratories, ensuring compliance is met and maintained.
