Concrete fiber engineered to replace steel mesh
Polyguard macro polypropylene fibers can reduce or replace conventional mesh and steel-fiber reinforcement in suitable slabs, shotcrete and precast sections, where the engineering design and the required residual performance permit — without corrosion, and with far less time spent on site.

The cost question
Steel is the cheapest part of steel
Compare the total installed cost of conventional reinforcement — not just the price of steel — with the Polyguard fiber solution.
A mesh layer arrives as a price per kilo and leaves as a price per square metre: transport, storage, cutting, lap waste, chairs and spacers, the crew that places it, the supervision that checks it, and the pour that waits for all of it. Fiber is dosed at the batching plant and none of that queue exists.
Where the structural design permits it, the fiber dose removes the mesh line item and everything attached to it. Where it does not, a designed fiber dose may still allow the mesh to be reduced, subject to the engineer's approval.

Product families
Innovative concrete solutions
Three families, one material science. Pick by the job the concrete has to do.
Advanced fiber reinforcement
Purpose-shaped geometries for shotcrete, precast units and thin sections where placing steel mesh is impractical.

Cost-effective fiber solutions
Potentially lower installed reinforcement cost than mesh or rebar where the design permits: nothing to cut, place, tie or chair, and, where no steel remains in the section, no concrete cover needed to protect it from corrosion.
View productsWho we are
Concrete that keeps its strength
Polyguard is the concrete- and asphalt-fiber brand of Lavan Plast. Our fibers are made on our own extrusion lines at the Tafresh plant in Markazi Province, from a polypropylene formulation developed for mechanical performance rather than for price.
That matters most where steel struggles: humidity, chlorides, sulfates, sustained heat and freeze–thaw. Polyguard fibers do not corrode, removing reinforcement corrosion as one potential source of cover damage, surface staining and premature repair.

Benefits of our products
A specialist manufacturer of concrete fibers under the Polyguard brand — engineered to reduce or replace crack-control reinforcement in suitable applications, with faster installation, no corrosion and a competitive installed cost.
- No corrosion, no rust staining, no corrosion-driven cover spalling
- Crack control in three dimensions, not just one plane
- Faster placement — no cutting, tying, chairing or lapping
- Alkali and chemical resistant in aggressive ground conditions
- Consistent dispersion — no balling at the specified dosage
- Engineering support: dosage design, trial mixes and site attendance
Where it is used
Six fields, one fiber platform
Industrial flooring
Warehouses, production halls, logistics yards.
Shotcrete
Tunnel linings, slope stabilisation, underground works.
Precast elements
Panels, culverts, pipes, segments and street furniture.
Large-scale slabs
Rafts, aprons, hardstandings and jointless floors.
Aggressive environments
Water, sulfates and chloride-rich ground conditions.
Fiber-reinforced asphalt
Heavy-duty pavements, bus lanes and port surfacing.
Where the money is
Four places fiber changes the budget
Each page follows the same structure: the expensive problem, the fiber solution, the cost lines that disappear, and the arithmetic.
Industrial flooring
Reduce total reinforcement cost by minimising or replacing conventional mesh where the engineering design permits.
Flooring economics
Shotcrete & tunnel
Less mesh handling, faster support cycles, lower labour requirement — more metres of tunnel completed per shift.
Cost per linear metre
Precast & facade
Fewer cracked units, less handling damage, a lower rejection rate — and more saleable production from the same moulds.
Rejection-rate economics
Fiber-reinforced asphalt
Drain-down control, mixture stability, fatigue and rutting resistance — and longer intervals between lane closures.
Lifecycle economicsDo the arithmetic
Four calculators, your own rates
Nothing is hard-coded. Put in your steel price, your labour rate and your dosage, and the comparison is yours to defend.
Flooring savings
Steel avoided, chairs and spacers, placing labour and lap waste against a fiber dose — per m² and per project.
Tunnel cost per metre
Mesh fixing hours, crew and equipment time, and the saving expressed per linear metre of tunnel.
Asphalt lifecycle
Added cost per tonne against postponed resurfacing over an analysis period you choose.
Precast production ROI
Rejection losses, rework and handling claims against the annual fiber investment — including the rejection cut needed to break even.
