Heavy Duty Perforated Plates

Q: What is the difference between heavy duty and heavy gauge?

Heavy duty describes the application requirement, while heavy gauge describes the thickness category. Heavy gauge perforated plate is commonly used for heavy-duty service.

Q: What thickness range can you make?

We produce thick gauge plates from 2.75mm to 30mm. We can recommend a suitable thick plate design based on your usage.

Q: What hole types are available for heavy duty applications?

Round, square, rectangular, hexagonal, and other patterns. Layout can be optimized (straight or staggered) to maintain strength for heavy-duty designs.

Q: What is the minimum hole size for thick plate punching?

A common guideline is hole diameter greater than or equal to plate thickness. We can advise a practical hole, pitch and bridge combination for thick gauge projects.

Heavy Duty Perforated Plate is commonly specified as a heavy gauge perforated plate or thick perforated plate when the project requires high rigidity, stable flatness, and reliable strength around the holes. It is a heavy-duty punched plate solution for applications where thin gauge sheets may bend, crack, or deform during service.

Thickness 2.75–30mm is available, with maximum sheet size up to 6000×1500mm (see the specification table above).

Heavy Duty vs Heavy Gauge: What Buyers Mean

In most sourcing scenarios, “heavy duty” refers to performance requirements (strength and durability), while “heavy gauge” describes the thickness category. A heavy gauge perforated plate is typically chosen to achieve a heavy-duty result—especially when impact, vibration, or structural load is involved.

Thick Plate Hole Pattern Engineering (Strength Comes First)

For thick perforated plate design, hole layout is not only about appearance—it determines bridge strength and service life. We can help you balance open area and plate strength by adjusting the key parameters below:

Hole diameter vs thickness: a common manufacturing guideline is hole diameter ≥ thickness.
Pitch & bridge (ligament) width: optimized to keep enough “steel bridge” between holes for heavy-duty use.
Edge margin: suitable edge distance reduces the risk of cracking at plate edges during punching or installation.
Layout options: straight or staggered layouts can be selected based on strength and functional needs.

Flatness Control for Heavy Gauge Plates

Dense hole patterns and thick gauge punching can introduce internal stress that may cause warping. For projects requiring better installation fit-up, we can provide leveling/flattening after punching to improve flatness (especially recommended for heavy duty perforated plates with dense perforations).

Material Options (Choose by Environment)

We offer multiple material options for heavy duty / heavy gauge perforated plate projects, such as Q345, mild steel (low carbon steel), stainless steel, and aluminum alloy. In general:

Mild steel / Q345: cost-effective for heavy-duty structural and industrial use.
Stainless steel: preferred for corrosion resistance (outdoor, chemical, wet environments).
Aluminum alloy: lighter weight where handling and corrosion resistance are priorities.

Fabrication Options for Installation

To meet real installation requirements, we can supply heavy gauge plates with additional processing:

Cut-to-size and custom outline shapes (based on drawings)
Deburring / edge finishing for safer handling
Bending for guards, covers, and panels
Rolling for cylinders and drums
Welding and assembly per drawings
Surface protection such as sandblasting and protective coating (as requested)

Triangular heavy-duty perforated metal plates; custom shapes available

Q1: What is a heavy duty perforated plate?
A1: A heavy duty perforated plate is a thick-gauge plate with punched holes, designed for higher rigidity, stronger bridges, and longer service life in demanding industrial environments.

Q2: What is the difference between heavy duty and heavy gauge?
A2: “Heavy duty” describes the application requirement (strength and durability), while “heavy gauge” describes the thickness category. In practice, heavy gauge perforated plate is commonly used for heavy-duty service.

Q3: What thickness range can you make?
A3: We produce thick gauge plates from 2.75mm to 30mm. Tell us your usage and we can recommend a suitable thick plate design.

Q4: What materials do you offer for thick gauge plates?
A4: Q345, mild steel (low carbon steel), stainless steel, and aluminum alloy. Material selection depends on corrosion, weight, and strength requirements.

Q5: What hole types are available for heavy duty applications?
A5: Round, square, rectangular, hexagonal, and other patterns. For heavy-duty designs, we can also optimize layout (straight/staggered) to maintain strength.

Q6: What is the minimum hole size for thick plate punching?
A6: A common guideline is hole diameter ≥ plate thickness. For thick gauge projects, we can advise a practical hole/pitch/bridge combination to ensure strength.

Q7: How do you handle warping on thick-gauge punched plates?

Heavy Duty Perforated Plate Manufacturing Video

This footage shows the real production process of our heavy duty / heavy gauge perforated plates, including punching, leveling/flattening and fabrication steps used for thick plate projects. Punching process for heavy gauge / thick plate Below is the production video of heavy duty perforated plates (punching process).

After perforation, especially for plates with very dense hole patterns, the perforated metal sheets will experience significant deformation. We perform flattening treatment after completing all perforation processes. Below is the video of flattening perforated metal sheets:

After the leveling process, our perforated metal sheets can be precisely laser-cut into any custom shape as required. Below is a production video demonstrating the laser-cutting process:
