Wide Variety of Premium Finishes to Match Any Style
We understand that surface preparation is not just about colour - it plays a vital role in design aesthetics, brand image, surface durability and customer satisfaction. That's why we offer a wide range of quality finish solutions to meet the needs of different architectural styles and environments.
Our standard finish options include:
Silver (Satin Chrome / Satin Nickel / Polished Chrome / SSS / PSS )
This is a timeless and versatile finish that blends well with modern minimalist interiors. Silver is often chosen for its clean look, corrosion resistance and to complement stainless steel fittings.
Black (Matte Black / Glossy Black)
This bold and elegant choice is quite popular in modern and industrial buildings. Matte black creates a delicate and non-reflective appearance, while bright black adds a striking high-end feeling. It is especially suitable for attic, luxury residence and high contrast design.
Gold (Polished Brass / Satin Gold )
The golden finish symbolizes luxury and tradition, making it perfect for classic interior design, upscale hotels, and decorative entrances. Our golden coating has anti rust properties, which can add high-end visual effects to your space without affecting its durability.
Antique Brass
This warm and ancient finish gives doors and furniture a vintage or classical style. It is typically used for restoration projects, boutique hotels, or historic buildings, where elegance and tradition are key.
Antique Copper
This texture is both rich and simple, adding a unique charm to interior decor designed with an artistic theme. It also hides fingerprints and wear marks, making it a choice that is both practical and beautiful.
Rose Gold
Rose gold has a modern and elegant tone with a soft metallic sheen. It is becoming increasingly popular in luxury interiors, designer retail spaces and bespoke residential projects. This colour shows character and style, while maintaining a very high quality of craftsmanship.
And there are also Antique Yellow Bronze, Pearl Nickel, and Oil Rubbed Bronze (ORB) etc..
All surface finishes are completed using advanced coating or plating techniques to ensure:
- Corrosion resistance
- Colour consistency
- Scratch resistance
- Long-term durability
We also offer custom finish matching for large-scale projects or special requests, helping architects and designers achieve exact color coordination across all hardware elements.
