Product Description

GALFAN Reno Mattress professional factory

The Reno mattress is a structure made of Mesh 6 hexagonal
double twisted wire mesh type as per ASTM A975-97 (Fig. 1
and 2). Reno mattresses are filled with stones at the project
site to form flexible and permeable, monolithic structures such
as river bank protection and channel linings for erosion control.
The steel wire used to manufacture the mattress is coated with
Galfan, a Zinc - 5% Alluminium Mischmetal Alloy. The standard
combinations of mesh and wire are shown in Tab. 2.
In order to reinforce the structure, all mesh panel edges are
selvedged with a wire having a greater diameter (Tab. 3).
Reno mattresses are divided into uniformly partitioned cells by
internal diaphragms.
Dimensions and sizes of Reno mattresses are shown in Tab. 1.

Wire
All tests on wire must be performed prior to manufacturing the
mesh.
1. Tensile strength: the wire used for the manufacture of
Reno mattresses and the lacing wire, shall have a tensile
strength not higher than according to ASTM A856. Wire
tolerances (Tab.3) are in accordance with ASTM A856.
2. Elongation: Elongation shall not be less than 10%, in
accordance with EN10223-3.
3. Galfan coating: minimum quantities of zinc shown at Tab.3
meet the requirements of Table 1 of ASTM A856.
4. Adhesion of Galfan: the adhesion of the zinc coating to
the wire shall be such that, when the wire is wrapped six
turns around a mandrel having four times the diameter of
the wire, it does not flake or crack when rubbing it with the
bare fingers, in accordance with ASTM A856.

All sizes and dimensions are nominal.
Tolerances of ± 3% of the width, length, and 2.5 cm of the
height shall be permitted.

Lacing Operations
Lacing operations can be made by using the tools shown in
Fig.5. Galfan coated steel rings having the following
specification can be used instead of lacing wire (Fig.4):
Galfan coated steel rings for products
• diameter: 3.05 mm, ASTM A313, Type 302, Class I
• tensile strength: 1530-1745 MPa, ASTM A764-93.
Spacing of the rings must not exceed 200 mm (Fig.3)
