Gabion & Reno mattress is
a galvanized double twisted hexagonal woven mesh compartmented basket
with a rectangular mattress shape. The compartments or cells of the reno
mattress are of equal size and dimension and are formed by internal
diaphragms. Gabion & Reno mattress have been used for channel
linings, river training, soil retention, slope stabilization and other
applications successfully throughout the world for over 100 years.
Double twisted gabion & reno mattresses offer
many advantages, such as flexibility, durability, strength,
permeability, ecology, reliability, longevity, low cost and an aesthetic
appearance. The thickness of gabion mats is usually between 0.15-0.5m.
It is similar to gabion box which could be divided by several cells and
adopts thicker diameter wires to form mesh edge.

A few days ago, it was learned from China National Heavy Duty Truck Corporation that the heavy-duty vehicle IV emission standard above 3.5 tons will be fully implemented as early as 2012 and will be implemented in 2013 at the latest. This news was confirmed by the relevant person from the Ministry of Environmental Protection.
At the end of 2009, the heavy-duty vehicle emission standard IV that was originally scheduled to be implemented on January 1, 2010 was delayed in the form of an undisclosed notification document. Afterwards, the topic of when China IV was implemented was always the focus of attention in the industry. In November 2010, China Aircraft Technical Service Center opened the registration of the National IV heavy-duty engine family declaration system. This incident was interpreted by many people as the next year's national IV emission standards will be implemented.
However, in early December 2010, according to the latest reports, the National IV emission standards will not be implemented until 2012 at the earliest. The Ministry of Environmental Protection has made a clearer statement on the implementation time, which is conducive to the preparation of vehicle and engine companies for production and technology research and development. It is understood that to maintain the normal operation of the State IV diesel engine SCR catalytic reduction device, trucks, passenger cars and other commercial vehicles must be able to add urea solution in time while driving, and at present there are only a few gas stations in major cities have urea filling stations; Coupled with the short-term national IV oil products are difficult to spread throughout the country, these are considered to be an important reason for the environmental protection department to delay the implementation of the National IV.
Flexibility
One of the most important advantages of
gabion & Reno mattresses is their flexibility both for the
individual unit and the overall. The construction of the units permits
it to tolerate differential settlement without failure. This property is
especially important when a structure is on unstable soil conditions or
in areas where scour from wave action or currents can undermine the toe
of the structure and cause structural settlement.
Durability
Gabions & Reno mattresses built from
high strength double twisted hexagonal mesh filled with natural hard
durable stone and connected together to create a monolithic mass
structure capable of undergoing structural movement without any loss of
structural integrity creating a highly durable structure.
Strength
Gabions & Reno mattresses possess the
strength and flexibility to withstand forces generated by water and
earth masses. The most important and relevant strength characteristics
pertaining to gabion and reno mattress design standards are the mesh
punch strength, the mesh tensile strength, the pull apart resistance
strength of the mesh, and the corrosion resistance of the mesh. The
strength values of the double twisted mesh are located within the
individual product specifications for each product and are represented
in ASTM A975-97.
