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.

Design


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.

Marking

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.
