Corrosion Protection

Plascoat® Coating – Built to Withstand, Designed to Last

At Sharp Metal Products, our in-house plastic coating plant gives us a clear edge over many competitors. We apply Plascoat®, a premium thermoplastic powder coating imported from the Netherlands, renowned for its unmatched performance in high-corrosion and coastal environments.

Plascoat® has consistently proven to outperform galvanising, conventional powder coating, and other protective finishes. It delivers long-term protection, exceptional UV resistance, and superior colour retention, even in the harshest conditions.

This makes it the ideal solution for applications like security fencing on coastal properties, where corrosion can rapidly compromise structural integrity. Backed by rigorous testing and real-world performance, our use of Plascoat® ensures every Sharp Metal product is built to last and engineered for resilience.

We tested the product ourselves at the Durban harbour. Our 7612 Vista-Mesh fence was installed at the Port in Durban, on the waters edge. 

The area is exposed to extremely harsh conditions including constant salt spray and industrial air pollutants from the daily shipping traffic.

While we were in the area, we inspected local fences installed nearby from a variety of other manufacturers and found them all to be either cracked, peeling or in advanced stages of white rust deterioration.

After four years in this climate, our product showed no signs of damage, colour fading, cracks or peeling and was simply wiped clean. The fence looks like it was installed yesterday!

Our Plascoat® Plastic coating plant runs batches of products in three colour options, and can also be pre-galvanized before being plastic coated.

Colours Available

Black - RAL 9005

Hot Dip Galvanizing

The hot dip galvanizing process entails a series of cleansing and pre-treatment techniques prior to coating steel with a thin zinc layer by passing the metal through a molten bath of high-temperature (450 °C) zinc.

Hot dip galvanizing provides ideal corrosion protection for steel – no other protective coating matches the unique protection gained by using this process. High adhesion, hard inner layers and a ductile surface layer are among the unique physical properties resulting from this process.

If there are suitable venting conditions, both internal and external protection on hollow structures can be achieved.

SMP has a long standing relationship with Durban Galvanizing who are trusted by steel fabrication industry leaders due to their continued quest for galvanizing excellence.

All Hot Dip Galvanized products supplied by SMP are dipped by Durban Galvanizing to the highest SABS-approved standards and certificates are available.
