What does WWF mean in construction?
2 Types of welded wire mesh. 2.1 Welded wire fabric (WWF) for concrete slab reinforcement. 2.2 Electro galvanized welded wire mesh with square opening.
What is WWF reinforcement?
Welded Wire Reinforcing, abbreviated WWR or WWF (Welded Wire Fabric), is generally used for reinforcing floor slabs. This type of reinforcing is made from a series of bars that run perpendicular to each other – in a grid layout. The bars are welded together to form a “sheet”.
What is weldmesh used for?
Steel weld mesh panels are used for security cages, aviaries, garden fences, garden screening, dog fencing, leaf covers for ponds, vegetable frames and around machinery in factories and production areas for health and safety.
What is welded fabric?
Welded wire fabric is a series of parallel longitudinal wires welded to cross wires by electric fusion method with accurate spacing. The welding work is done by machinery which ensures the precise dimensions and results in considerable savings in time, labour and money.

Is fiber mesh better than wire mesh?
Instead of laying down a wire mesh before the concrete is poured, using fiber mesh involves mixing in different fibers such as glass, steel, synthetic fibers, or natural fibers. In addition to providing a more thorough protection for your concrete pour, fiber mesh typically takes less time than wire mesh to use.
Why is wire mesh so expensive?
That said, other than the threaded wires throughout the loom, the weaving process of woven wire is mostly automated. With that, the labor costs and heavy-duty wire that must be used causes welded mesh to be the more costly of the two.
Can you weld in polyester?
The two most common injuries associated with welding operations burns to the skin and eyes. For protection from injury, the welder should always wear: Never wear synthetic materials such as polyester or polyester blends since they will ignite and burn rapidly.
How big is a sheet of WWF?
5′ x 10′
Our standard sheet size, 5′ x 10′, is always in stock and available for order. 8′ x 20′ and 8′ x 15′ sheet sizes and custom W/D Designations must be special ordered. WWF consists of wires arranged in a square or rectangular grid configuration.
