Rilsan Coating

Rilsan Coated Fasteners Manufacturer in India

BRK Industries is a trusted Rilsan Coated Fasteners Manufacturer and Exporter in India, supplying premium-quality bolts, nuts, washers, threaded rods and industrial fastening solutions with a high-performance polyamide (nylon) coating.

Rilsan Coating is a durable polyamide 11 (PA11) protective coating that provides outstanding resistance against corrosion, chemicals, abrasion and impact. Unlike metallic coatings, Rilsan forms a flexible and uniform polymer barrier around the fastener, making it an excellent choice for demanding environments such as marine installations, chemical plants, water treatment facilities and outdoor infrastructure.

Our Rilsan-coated fasteners are manufactured to international quality standards and supplied to industrial customers across domestic and global markets.

What is Rilsan Coating?

Rilsan Coating is a thermoplastic polyamide (PA11) coating applied to steel fasteners to create a durable protective barrier. The coating offers excellent resistance to moisture, chemicals and mechanical wear while maintaining long-term performance in aggressive environments.

Unlike conventional zinc coatings, Rilsan provides both corrosion protection and electrical insulation, making it suitable for specialized industrial applications.

Why Choose Rilsan Coated Fasteners?

Excellent Corrosion Resistance
Superior Chemical Protection
High Abrasion Resistance
Impact Resistant Finish
Electrical Insulation
Long Outdoor Service Life

Rilsan Coating Process for Fasteners

Every Rilsan Coated Fastener manufactured by BRK Industries follows a controlled coating process to ensure uniform coverage and long-lasting performance.

1 Surface Preparation

Fasteners are cleaned thoroughly to remove grease, oil and manufacturing contaminants.

2 Surface Conditioning

The steel surface is prepared to ensure strong coating adhesion.

3

Preheating

Fasteners are heated to the required temperature before coating application.

4

Rilsan Coating Application

The polyamide coating is applied using a controlled coating process that creates a uniform protective layer around the fastener.

5

Cooling & Curing

The coated fasteners are cooled under controlled conditions to achieve a durable finish.

6

Quality Inspection

Each batch undergoes coating thickness inspection, adhesion testing and visual quality checks before dispatch.
