Perforated Metal: What We Do with Hundreds of Thousands of Holes
Perforated metal is at the core of what we do at Webforge Locker. From intricate architectural designs to heavy-duty industrial applications, it’s a process we’ve refined over decades — and it all starts with punching thousands of holes.
So, how does it work? What can it do? And why are we so passionate about it? Let’s take a closer look.

How Perforation Works
At its simplest, perforating metal involves using hydraulic machinery made up of a punch and a die. The punch pushes through the material, creating a clean hole and ejecting the leftover metal (called a “slug”) through the die.
For large-scale projects, our mass perforation machines can deliver up to 500 hits per minute, forming multiple rows of holes at once. That’s hundreds of thousands of holes in just a matter of minutes. For more detailed or custom architectural projects, we use linear punch presses that allow for unique, flexible patterns and designs — with either standard or custom-made dies.

Pic-Perf: Turning Perforation into Art

Perforation isn’t just functional — it can be beautiful too. That’s where Pic-Perf comes in. This innovative technique transforms standard perforated sheets into detailed visual designs, using varying hole sizes to recreate abstract or figurative images.
It’s all about smart preparation. We take your supplied image, convert it into a digital format, and feed it into our software. The result? A high-impact visual element built right into the metal — no additional printing or overlay required.________________________________________
What Happens to All the Metal We Punch Out?
Every slug of metal removed during perforation is recycled. Where we send it to a foundry where it’s melted down and reused.

Why Use Perforated Metal?
Perforated metal combines strength, flexibility, and customisation — making it one of the most versatile materials on the market.
You can choose from our library of standard patterns, or we can create something completely bespoke. Want your perforations in the shape of stars, leaves or logos? If you can draw it, we can punch it.
Beyond aesthetics, perforated metal offers:
Structural benefits: Curving or folding sheets adds rigidity and reduces the need for extra supports.
Cost savings: No need for bulky frames — perforated sheets are easy to install.
Longevity: Aluminium, our go-to material, is corrosion-resistant and designed to last 50+ years.
Sustainability: Lightweight panels put less strain on buildings and are fully recyclable.

Where Perforated Metal Goes: From Stadiums to Sugar Mills
Perforated metal finds a place in both industrial and architectural environments.
Industrial uses include:
• Pulp and paper filtration
• Sugar cane processing
• EMI/RFI shielding
• Automotive transmission linings
• Speaker grills
Architectural applications include:
• Ceilings and wall panels
• Balustrades and bridges
• Privacy screens and partitions
• Sunscreens and building facades
Often, it plays a dual role — providing both function and form. For instance, it can reduce solar heat gain while adding texture and visual interest to a building’s exterior.
