Pultruded Products and Moulded Gratings

Overview

Pultrusion is a composite of different materials and reinforcements. As such, the designer is empowered with a freedom of design that enables the selection of reinforcements, resin, systems, shape and loadings to yield a wide range of performance characteristics. Any profile can be produced that has mechanical properties comparable to metals. Notwithstanding the composite, matrix can be formulated to meet the most demanding chemical, flame retardant, electrical and environment requirements.

Pultruded profiles are fabricated by ‘pultruded process’ through a CNC operated pultrusion machine, combining a resin matrix with fibre reinforcement. Continuous fibre reinforcement in roving or mat roving form is drawn through a resin bath, which coats each fibre with a specially formulated resin mixture that can be colour pigmented.

Pultrusion Products

Specifications

Extraco FRP Grating products are designed and used like traditional metal grates but with the inherent benefits of fibreglass. They are ideal replacement for steel and aluminium gratings in corrosive environments or anywhere frequent grating and walkway replacement costs are unacceptable.

Reliable performance
High impact and fatigue strength
Slip resistance
Ultra-violet resistance
Light weight
Easy installation
Low smoke/low toxic emissions

Flame resistance
Maintenance Free
Long lifetime
Cost effective solution
Corrosion resistance
Fire retardance
Non-conductivity

Extraco FRP Grating products are designed to withstand extended contact with direct flame without burning or incurring structural damage, thus providing a safe pathway to exit. Moreover, the surface grit-bonded with resin ensures extended protection against toxic emission and flame spread.

FRP Pultruded Gratings

FRP pultruded grating is stronger than steel yet 1/3 times lighter, non-corrosive and provides a safe, non-skid surface for service personnel. It does not conduct electricity or produce sparks.

FRP Pultruded Handrails

FRP Pultruded Ladders

Pultruded Type ladders are commonly used where strength and Chemical Resistance are required.
They are fabricated by 'pultruded process' through a CNC operated pultrusion machine.
Corrosion resistance is achieved by using proper raw materials (Vinylester Resin and 'C' Surface Veil).
Tube: 50 x 50 x 4mm.
Rungs: Solid Round rods of 32mm.
Pultruded profiles are composed of 35% Resin/filler to 65% glass fibre.
The Profiles shall be conducted of glass roving, continuous strand mat and covered by 'C' surface veil. The veil, along with UV inhibitors, provides a greater corrosion capability for harsh chemical environments and creates a ultra-violet barrier for continuous exposure.
Assembly of ladder parts incorporates a two-part mechanically bonding with epoxy and S/S pins.

FRP ROOF STRUCTURE

Pultruded Roof Structure using a safety factory of four-to-one are designed to support wind load and extreme temperature on the outside while withstanding corrosive environments from the inside. Columns, beams and purlins perform in the building construction the best way. Virtually, maintenance-free and non-conductivity makes the system the ideal choice for construction.

FRP WINDOW / DOOR FRAMES

Pultrusion moves the non-metal windows/doors to a new range of performance. Fibreglass/Polyester Resin Pultrusion form frame and parts, components and spacer bars in a new generation of thermally efficient, dimensionally stable window frames.

FRP STANDARD STRUCTURAL

From small rod and flat sheet to angles, tubes, pipes and huge ‘I’ beams, pultruded structurals are available with no limitation. With strength that allows substitution for steel structurals, fill the demand for all types of fabricated building structures in most industries.

MOULDED GRATING

Extra co moulded fibreglass grating is a strong, highly reliable mesh grating panel which allows efficient on site cutting to minimize grating waste. It is the chemical resistant flooring choice for many Industrial applications. Load bearing bars in both directions allow for use without continuous side support. A higher safety factor is achieved by designing in higher glass content at the bottom of the grating for greater tensile strength.

FRP moulded grating is engineered to provide maximum corrosion resistance in tough conditions such as chemical plants, sewerage treatment plants, etc.

The higher glass to resin ratio of pultruded grating results in sections with higher structural properties than moulded sections of similar depth and weight because of longer span capability, support structures can be reduced, resulting in lower total cost when using pultruded grating instead of moulded.

The corrosion resistance of pultruded grating is considered to be outstanding and far superior to galvanised steel, aluminium or stainless steel, although it is less than moulded grating. Moulded grating is engineered to provided maximum corrosion resistance in tough conditions such as chemical plants, etc.

MOULDED LADDERS

Extra co standard width of moulded ladders is 300mm, 400mm & 500mm wide. Maximum length of one ladder is 5000mm.
