About Pultrusion & FRP Fencing

Pultrusion is a manufacturing process that creates fibre-reinforced plastic (FRP) parts with a consistent cross-section. It is a continuous, automated process that uses a heated die to shape the composite — converting fibre reinforcements and resin matrices into finished composite parts. The pultrusion process involves pulling the fibre reinforcement through a heated die using either continuous strand mats or rolls of filament.

Pultrusion machines are available in India and from overseas. Pultruded FRP (fiberglass-reinforced polymer) products can last 20–30 years, or even over 40 years depending on the type of FRP and the conditions it is used in. The three types of roving used in pultrusion are smooth roving, textured roving and monofilament roving.

The pultrusion process is mainly used to produce FRP fencing railing — the most common FRP fence product. The FRP/GRP fencing railing can be used as road dividers and industry guardrails on account of their solid structure. Infill sections can be circular, square and rectangular tubes.


Why a Paint Booth for FRP Fence Painting?

Even today, painting of FRP components is done in a very crude technique by smaller FRP vendors who do not have a dedicated FRP Fence Paint Booth. Spray Booths for FRP Boundary Fences in India are now recognised as an important requirement for good finishing technique.

✗ Old Method — Brush Painting
  • Time-consuming and labour-intensive
  • Does not give the required finish quality
  • Uneven colour coverage on all sides
  • No overspray control — messy environment
  • Crude technique — no quality standard
  • Paint does not penetrate textured FRP surface evenly
✓ Spray Booth for FRP Fence
  • Even surface painting on all sides of components
  • Clean finish with controlled overspray
  • Faster than brush painting — higher throughput
  • Consistent finish quality across production runs
  • Operator safety — fumes extracted efficiently
  • Meets pollution norms for particulate matter

FRP Fence Painting – Booth & Process

Pultruded FRP painting is manufactured in two parts — the main columns and the internal/grated sections separately. After the manufacturing process is completed and the product has cooled off, most components are painted in a Paint Booth for Pultruded Products.

Most manufacturers of FRP Fence use mat black paint for their components as the use of glossy paints tends to become dull in open air. For the fence to look new and beautiful, mat black paint often serves the purpose. Maximum care must be taken while selecting the black paint — it must dry fast and create dry, non-sticky dust from the overspray.

The grated middle section of the FRP fence is painted horizontally while the main box sections are painted vertically. Paint sprayed in a Spray Painting Booth for FRP Fence creates an even surface painting on all sides of the components — producing a clean finish with visible texture that gives the FRP fence its distinctive appearance.


Two Methods of FRP Component Painting

FRP components are painted using two methods — each suited to different production requirements and finish specifications:

Gel Coat Application Method

In-mould FRP finishing

Gel coat is applied over the FRP moulds and the moulds are kept in an FRP Fencing Railing Booth during the application and setting process.

  • Applied directly over FRP mould surface
  • Controlled environment in fencing railing booth
  • Excellent in-mould colour and surface quality
  • Suitable for smooth finish GRP/FRP products
  • Commonly used for moulded FRP panels

Direct Painting Method

Post-manufacture spray painting

Applied after the product is manufactured — a series of grinders and buffs are used to create a smooth surface before multiple layers of thick paint are applied.

  • Surface prep with grinders & buffs first
  • Multiple layers of thick mat black paint
  • Vertical painting for main box columns
  • Horizontal painting for grated mid-sections
  • Applied in dedicated FRP Fence Paint Booth

Equipment Required for FRP Fence Spray Painting

For the spraying of mat black paint on pultruded fencing, the following accessories are required alongside the dedicated FRP Fence Paint Booth:

  • FRP Fence Painting Booth (Dry Back or Water Wash type)
  • Pilot spray gun for precise paint application on FRP profiles
  • Air hoses — suitable length for booth dimensions and component reach
  • Air compressor with adequate capacity for continuous spray painting
  • FRL unit (Filter-Regulator-Lubricator) to remove water and moisture from compressed air
  • Mat black fast-drying paint suitable for FRP/GRP substrate
  • Grinders and buffs for surface preparation (direct painting method)
Autocoat’s Experience in FRP Fence Paint Booths

Frequently Asked Questions

What is an FRP Fence Painting Booth? +
An FRP Fence Painting Booth (also called Spray Booth for Pultruded FRP Fence or FRP Fencing Railing Booth) is a specialised spray painting enclosure designed for painting pultruded FRP fencing components — including box section columns and grated infill sections. It provides even surface painting on all sides, controlled overspray capture, operator safety and pollution norm compliance — delivering a consistently clean mat black finish.
What is the Pultrusion process and why does it need a Paint Booth? +
Pultrusion is a continuous, automated manufacturing process that creates fibre-reinforced plastic (FRP) parts with a consistent cross-section by pulling fibre reinforcements through a heated die. The resulting pultruded FRP fence sections — columns, grating and railings — require painting after manufacture. A dedicated Paint Booth is required because brush painting is time-consuming and does not give the required quality finish. Spray painting in a booth gives even coverage on all sides, faster throughput and a consistently professional result.
What paint is used for FRP fence spray painting? +
Most manufacturers use mat black paint for FRP fence components — as glossy paints tend to become dull in open-air conditions. The mat black paint must: (a) dry fast, and (b) create dry, non-sticky overspray dust during spraying. Maximum care must be taken in paint selection to ensure these properties. The paint is applied using a pilot spray gun with air hoses and an air compressor fitted with an FRL unit to remove water moisture from the compressed air supply.
What are the two methods of painting FRP components? +
FRP components are painted by two methods: (1) Gel Coat Application Method — gel coat is applied over FRP moulds kept in an FRP Fencing Railing Booth during application; and (2) Direct Painting Method — after the product is manufactured, the surface is prepared using grinders and buffs, then multiple layers of thick paint are applied in a dedicated FRP Fence Paint Booth. The grated mid-sections are painted horizontally while the main box columns are painted vertically.
What equipment is needed for FRP fence spray painting? +
The required equipment includes: a dedicated FRP Fence Painting Booth, a pilot spray gun, air hoses, an air compressor with adequate capacity, and an FRL unit (Filter-Regulator-Lubricator) to remove water and moisture from compressed air. Additionally, grinders and buffs are needed for surface preparation in the direct painting method, and fast-drying mat black paint suitable for FRP substrates.
