FIBER GRC / GRP PLANTERS

GRC and GRP are extremely versatile materials for planter manufacturing, being lightweight, strong, and moldable into almost any design.

Glass-fiber Reinforced Plastic (GRP / Fiberglass)

It is similar to GRC in essential composition, except that the binder in fiberglass planters is polyester or epoxy resin rather than cement.

Glass-fiber Reinforced Concrete (GRC)

GRC is a high-strength composite material made from cement mortar reinforced with bundled strands of glass fiber filaments.

GRC and GRP are largely interchangeable for many generic planter applications as both materials are:

• Moldable
• Weatherproof and water resistant
• Custom colour options (either within the material itself or via an exterior paint finish)
• Similar in cost
• Economical for large-scale production

Bespoke manufacturing in either material requires an initial investment in molds, which makes the unit cost lower for larger production volumes.

Manufacturing at JP Planters

JP Planters is engaged in manufacturing GRC and FRP elements in a modern and advanced production facility.

We use high-quality composite materials made from:

• Premium White Cement
• Fine Quartz Silica Sand

• Water

Tailor-Made Designs

Planters can be molded into any shape, size, color, texture, or finish, depending on the requirements of architects and designers.

High-Quality Fiber Materials

We use international standard materials for our fiber planters.

Most commonly used materials include:

• Owens-Corning Matt
• ISO Resins
• Branded pigments
• PU coatings that are UV and frost resistant according to European standards

Materials are sourced from reputed companies such as:

• Axalta

• Asian Paints

Highly skilled paint technicians with automotive-grade finishing expertise are employed to deliver premium paint quality.

Advantages of GRP Planters

• More intricate and detailed moulding compared to GRC
• More refined and sophisticated surface finish
• Lighter weight compared to GRC planters

Advantages of GRC Planters

• More natural and stone-like appearance, especially when colour-tinted
• Stronger material suitable for larger structural mouldings
• Heavier than GRP but 75–80% lighter than precast concrete
• Higher density and better impact resistance (ideal for public spaces)
• Fire resistant — does not burn or emit smoke when exposed to fire

Typical Applications

GRP Planters

• Residential projects
• Interior landscaping
• Light commercial applications
• Decorative moulded designs

GRC Planters

• Public spaces
• Outdoor landscaping
• Heavy-duty environments
• Alternative to precast concrete

CORTEN PLANTERS

Corten steel, also known as weathering steel, is a special type of steel originally developed for bridges and skyscrapers due to its exceptional strength.

When exposed to the environment, it develops a protective rust-like patina that creates warm, rich textures not usually associated with metal.

Due to its chemical composition, a dense oxidation layer forms during the weathering process, protecting the steel beneath. If this layer is damaged, a new protective layer naturally forms.

Corten steel has significantly higher resistance to atmospheric corrosion than ordinary steel.

Unique Features of Corten Steel

Outstanding Corrosion Resistance

Corten steel offers corrosion resistance up to 8 times greater than standard steel, making it ideal for harsh climates such as humid areas, coastal zones, and wind-sand environments.

Cost Efficiency

Corten steel is more affordable than stainless steel, while still offering excellent corrosion resistance.

Wide Variety of Colours and Patterns

Our factory offers pre-treated Corten surfaces that provide different colour patterns during the weathering process.

Low Maintenance

Due to its corrosion resistance, maintenance is minimal. Only occasional cleaning and inspection are required.

High Malleability

Corten steel can be easily laser-cut into intricate shapes and patterns, making it perfect for decorative landscaping and fire pit designs.

Corten Steel Weathering Process

Stage 1: Freshly manufactured Corten steel with dark oily residue.

Stage 2: The residue begins breaking down as weathering starts.

Stage 3–4: Run-off stage where oxidation develops (may take 3–9 months depending on climate).

Stage 5–6: Final weathered patina forms with a stable, uniform appearance.

ALUMINIUM PLANTERS

Benefits

Aluminium has several advantages for planter fabrication:

• Does not corrode when exposed to weather
• Higher strength-to-weight ratio than steel
• Approximately 30% more expensive than powder-coated steel

Raw Aluminium Finish

Planters can be supplied without coating, allowing them to develop a naturally weathered appearance over time.

To preserve the original finish, we often apply a clear protective lacquer coating.

Powder-Coated Aluminium

Aluminium planters can be powder-coated in any RAL colour or special textured finishes.

Unlike steel, aluminium does not corrode even if the paint surface is scratched, making it ideal for high-traffic areas.

Technical Details

Material: 2 mm aluminium (up to 6 mm available)
Coating: Clear coat or powder coat
Construction: Smooth corners and edges
Surface Finish: Matte, satin, gloss, metallic, or special finishes
Suitability: Indoor and outdoor environments

GALVANISED ZINC PLANTERS

These industrial-style planters are manufactured from premium hot-dipped galvanised steel, giving them a distinctive industrial aesthetic.

Galvanised zinc enhanced with chromium helps maintain its shine and durability.

These planters are suitable for large indoor plants and small outdoor trees, available in both assembled and dismantled forms.

Features

Drainage System

Each planter includes drainage holes to allow rainwater to escape.

Protective Lining

We recommend adding a protective liner before placing soil and plants.

These planters look excellent on decking, patios, gardens, or grass landscapes.

Properties of Galvanised Zinc

Durability: Reliable and predictable coating performance.

Low Maintenance: Requires minimal upkeep.

Long Life:

• Over 50 years in rural environments
• 20–25 years in urban or coastal areas

Tough Coating:
The metallurgical bond provides excellent resistance to transport and installation damage.

OTHER ALLIED PRODUCTS

Fire Pits

Fire pits are an essential outdoor entertainment feature, providing warmth and ambiance year-round.

They typically consist of a round or square container where fuel burns to generate radiant heat.
