Hot dip Galvanized PTFE and Zinc coating

Coating Services Offered by Shreehari Engineering
At Shreehari Engineering, we specialize in providing high-quality surface coatings on fasteners to enhance their durability, corrosion resistance, and performance across various industrial environments. We offer the following coating options:

Hot Dip Galvanized (HDG) Coating:
Shreehari Engineering offers Hot Dip Galvanized fasteners that are coated with a thick layer of zinc through an immersion process in molten zinc. This ensures long-lasting protection against rust and corrosion, especially in outdoor, marine, and industrial conditions.
Key Benefits:

High corrosion resistance

Durable and weather-resistant

Ideal for heavy-duty applications

PTFE Coating (Polytetrafluoroethylene):
Our PTFE-coated fasteners are designed for critical environments requiring chemical resistance and low friction. The PTFE layer prevents seizing, galling, and ensures easy installation and removal, even after long-term exposure.
Key Benefits:

Excellent resistance to chemicals and solvents

Non-stick and low-friction surface

Withstands extreme temperatures and pressures

Zinc Coating (Electroplated):
Shreehari Engineering also supplies zinc-coated fasteners that offer reliable corrosion protection for general-purpose and indoor use. The electroplated zinc layer acts as a sacrificial barrier to protect the base metal.
Key Benefits:

Economical corrosion resistance

Smooth and clean surface finish

Suitable for light-duty industrial and commercial uses
