📍Guangzhou | Exhibition

Amid the constant flow of visitors,
what truly makes people stop is not the crowd — but something worth validating.

At our booth, one question keeps coming back:

Can the drilling performance of a bimetal screw truly be trusted?

A stainless steel body, seamlessly welded with an alloy steel tip —
not just a combination of materials, but a balance of precision and reliability.

We believe:
Performance speaks best when it is proven, not promised.

Now, live demonstration.
Let the result speak for itself.

Bimetal Screws on the Road | Guangzhou | May 8–10

The journey continued.
Back in Guangzhou, our bimetal screws returned to one of our most important annual exhibitions — the 15th Steel Structure Expo at Pazhou.

This is where we strengthen our domestic market presence every year, bringing bimetal technology to more customers and turning awareness into real understanding.

At the booth, discussions went deeper — from product basics to real applications and performance.
Curiosity led to insight, and insight opened new possibilities 🔩

Guangzhou is not just a stop — it’s our foundation.
The journey goes on ✈️

Happy Monday. This batch of bimetal self-drilling screws is already on its way.​

Fastening is often seen as a simple action. In reality, it is a decision — one that balances strength, corrosion resistance, and installation efficiency over time. Bimetal construction is not just about combining materials, but about defining a stable boundary between different performance demands.​

Stainless steel stands against time and environment. Alloy steel delivers instant pe*******on and grip. One serves durability, the other ex*****on. True reliability emerges not from extremes, but from how these roles work together.​

We don’t design for passing tests — we design for performance that holds in real structures.​

We’ll also be presenting this thinking at our exhibition in Pazhou, Guangzhou from May 8–10.

Looking forward to meeting you and exchanging ideas beyond the drawings.​

Bimetal has a strong drilling ability and can pe*****te 4mm and 6mm steel plates, thanks to its tail made of alloy steel.

At the same time, it has excellent anti-corrosion ability and has an SGS-certified 1500h salt fog-proof test. This is due to its substrate made of stainless steel and a special polymer anti-corrosion coating.
