GRC - GRP

GLASS-FIBRE REINFORCED CONCRETE

Glass-fibre Reinforced Concrete (GRC) is the general term for a high-strength composite stone made with cement mortar (mainly a mixture of cement, sand and other additives) reinforced with bundled strands of fibreglass filaments. GRC differs from what most people refer to as ‘fibreglass’ in that cement mortar is used as an alternative of a plastic resin (e.g. polyester) for encapsulating the fibreglass elements. Unreinforced concrete is strong in compression but weak in tension. This is why reinforcement is added. Precast concrete is typically reinforced with steel, but precast concrete products are very heavy because of their overall thickness.

Adding glassfibres overcomes this weight problem while dramatically increasing the tensile strength of concrete. The glassfibre strands in the cement-sand mortar (3-5% by weight depending on the process) reduce product weight because of the much thinner but stronger wall sections. GRC products are typically only 20-25% of the weight of traditional precast concrete products. This lightweight feature of Glass Reinforced Concrete moreover makes it safer and easier to handle on site, and eases loads on structures when installed.

ENVIRONMENTALLY FRIENDLY 'MADE IN USA' PRODUCTS

The main constituents of GRC are based on the naturally occurring earth oxides that are used in the production of cement and glass fibres. These are not generally regarded as pollutants. The main reasons for the reduced eco-friendly impact of GRC compared to traditional precast concrete are: reduced cement usage per product & reduced transport costs These advantages and benefits make GRC a perfect material for the manufacture of planters, planter boxes, street furniture, architectural mouldings and panels.

ADVANTAGES AND BENEFITS OF GLASS-FIBRE REINFORCED CONCRETE

Mouldable

GRC can be moulded to precisely reproduce almost any small or large shape (eg. curves, patterns, reliefs, etc).

Colour

GRC products can be manufactured using different cements (eg. white, off-white, grey) that can be coloured with mineral oxides.

Impact resistant

GRC products are highly durable. They will not break upon impact, and any localized damage can usually be repaired.

Weather-proof

GRC will not rust or rot, it needs no painting, and because it doesn’t contain reinforcing steel it won’t develop ‘concrete cancer’.

Water resistant

GRC is virtually impermeable to water thus making it ideal for products such as planters and water-features. Usually no additional waterproofing is required.

Chemical resistant

the high density and high cement content of GRC give it a higher chemical resistance than other cement based materials.

Fire resistant

GRC does not burn or emit smoke when exposed to fire. This provides architects and designers superior flexibility in specifying components to satisfy fire performance requirements.

GLASS REINFORCED PLASTIC GRP

Glass Reinforced Plastic (GRP) may be a very useful material within variety of various and diverse industries. Starting from hotels to construction, marine docks to education, GRP is extremely versatile and might be easily tailored to any location within any industry. GRP products are growing in their use and recognition, which is right down to the extensive list of benefits that GRP offers to any application. The distinctive qualities of GRP makes it a particularly desired material to be used.

High Strength to Weight Ratio

GRP may be a lightweight material that's also strong and might bear heavy loads. Pound for pound GRP is stronger than steel. Thanks to being so light, this makes it easy to move and install, requiring less man power than if steel was used instead.

Low Maintenance

GRP has virtually no maintenance, or maintenance cost, involved. It is a hardy material which might withstand conditions outside with little or no wear and tear. Many GRP products including gratings, handrails are all commonly installed outside in areas of high footfall or with greater volumes of daily traffic.

Affordable

Often construction materials may be expensive. GRP gives get great value for money. It also requires next to no maintenance or upkeep, so this protects on additional costs. GRP lasts for an extended time and this suggests that there's no have to spend extra money replacing this product regularly.

Versatile

As a results of the moulding process that GRP is subjected to, it can take the form of any container. This ensures that each one GRP products are made to an actual size to ensure the right fit. Not only this, but it allows GRP the flexibleness to be moulded to any specification.

Corrosion Resistant

The resins employed in GRP offer corrosion resistance over a good pH range. Although GRP is corrosion immune to variety of various chemicals, you'll request test results on all chemicals if required.

UV Stability

GRP products are manufactured with a high-quality UV inhibitor to forestall any UV degradation from going down.

Durability

All GRP products are extremely durable. They’re all able to withstand any wear and tear, pressure or damage. GRP products are long lasting. Unlike other materials which will deteriorate, GRP products are designed to be durable irrespective of the environment they're installed in.

Weathers Well

The unique properties of GRP mean that the condition of the merchandise hardly deteriorates when exposed to the weather. GRP are often outside, no matter rain or shine, and remain undamaged and unaffected by the environment.

Anti-Slip Finish

GRP are often manufactured with various finishes. One of the most popular is that the anti-slip surface which provides grip and stability, even when wet. Unlike steel, which may become hazardous when wet, GRP remains a secure and secure product to use in any wet or damp conditions.

Low Residual Value

GRP has low residual value in construction, unlike copper and steel, which suggests your GRP products are unlikely to be stolen and sold on.
