Composite masonry mesh ROCKMESH

Corrosion of steel concrete reinforcement occurring due to moist environment, chemicals or salts can be a reason for extensive damage and failure of reinforced concrete structures, such as concrete covers, areas characterized by increased moisture, harbor works, floors at manufacturing facilities, highway concrete coatings, etc.
Specific problems arising due to the use of metal reinforcement led to search for alternative solutions. ROCKMESH composite mesh is proposed by Galen LLC as one of the best substitution products for steel construction elements.

Intended use

ROCKMESH is designed to replace conventional metal mesh used for reinforcement of various construction structures.


Composite masonry mesh ROCKMESH

ROCKMESH consists of the following components:

- BFRP bars, arranged in the perpendicular pattern to each other;
- Plastic fixings in the bars cross points.

ROCKMESH is supplied as a ready-to-use solution: in rolls or sheets thus speeding up construction operations.


Rockmesh Bk (2,2-50)/(2,2-50)*50*150, where:
Rockmesh Bk composite BFRP mesh in sheets (Rockmesh Bp in rolls);
(2,2-50)/(2,2-50) bar diameter and length of each opening side, mm;
50 mesh width, cm;
150 mesh length, cm.

For individual projects of the customers it is possible to produce of various bar diameters and opening sizes.

Fields of application

Residential and civil construction:
  • Reinforcement of concrete structures: internal and external wall panels,
  • including reinforcement of multilayer panels, floor slabs, beams;
  • Reinforcement of concrete floors;
  • Reinforcement of brick and masonry walls of buildings and structures;
  • Reinforcement of decorative concrete and plaster elements; Reinforcement of other construction elements from concrete, plaster.
Industrial engineering:
  • Reinforcement of concrete structures: internal and external wall panels, including reinforcement of multilayer concrete wall panels, beams;
  • Reinforcement of concrete floors;
  • Reinforcement of hydraulic structures, waterside structures;
  • Reinforcement of brick and masonry walls of buildings and structures;
  • Reinforcement of decorative plaster articles; Reinforcement of other construction materials manufactured from concrete, plaster.
Road construction:
  • Reinforcement of road slabs;
  • Reinforcement of automobile roads, bridges; Road and railroad safety guardrails.
Construction of bridges and hydraulic structures:
  • Reinforcement of bridge deck slabs;
  • Reinforcement of pedestrian footpaths;
  • Reinforcement of onshore facilities;
  • Construction of berths, dams, reservoirs, fountains, etc.

The masonry meshs advantages:

  • High tensile strength: composite armature is capable of withstanding higher loads in tension, bending and tearing out of a wall than metal one, i.e. it is 3 times stronger;
  • igh corrosion- and chemical resistance: excellent capacity to resist the impact of chemicals, salts and corrosion process even in high moisture & aggressive mediums;
  • Low mass: weight of the most common metal mesh (50*50*3 mm, 0,5*2 m) is 2.22 kg/m2, a similar mesh made of composite material weighs 300-360 g/m2, i.e. it is 6 times lighter;
  • Low thermal conductivity: 0.46 W/m2 of a composite mesh, and 40-60 W/m2 of a metal mesh, i.e 100 times higher than that of metal mesh. This means that metal mesh in walls act as thermal bridges and reduce the thermal efficiency of a building. Composite mesh helps to eliminate this disadvantage;
  • Reliable & durable: according to investigation reports by The University of Sheffield (The UK) the coefficient of strength reduction in moisture conditions within 100 years equals to 1.25. This corresponds to strength retension of 79.6%;
  • Dielectric;
  • Non magnetic;
  • Eco-friendly: emissions of carbon dioxide during production of composite mesh is 40 times lower than that for metal one;
  • Low elasticity modulus allows to damp vibration smoothly;
  • Retains its shape at concrete structure damages that prevents further structure failure.
