RajFilters & Wiremesh Pvt. Ltd. is a leading manufacturer and supplier of high quality metal perforated sheets in India. With more than 40+ years of manufacturing expertise, we provide precision-engineered stainless steel, mild steel, and aluminium perforated sheets, as well as customized perforated metal products for industrial and commercial applications.
Our perforated sheets are manufactured with advanced CNC punching machines to ensure precise hole patterns, consistent spacing, and excellent dimensional stability. These sheets offer superior strength, excellent ventilation, and efficient filtration performance, making them suitable for a wide range of industries.
We manufacture perforated sheets in various materials, thicknesses, hole patterns, and sizes to meet our customers’ specific requirements.
Selecting the correct perforated sheet is important for proper performance, strength, air and liquid flow, filtration, and sorting. Different applications require different hole sizes, patterns, pitches, and sheet thicknesses. Below are the important factors to keep in mind while selecting a perforated sheet.
Hole size is one of the most important factors in perforated sheets. The hole size should be selected based on the material passing through the sheet, airflow, filtration requirements, and the sheet’s strength.
Smaller Hole Size:
Larger Hole Size:
We manufacture perforated sheets in various hole sizes as per customer requirements.
Pitch means the distance from the centre of one hole to the centre of the next hole.
Correct pitch selection is important for sheet strength, open area, and performance.
Smaller Pitch
Larger Pitch
Pitch size should always be selected according to the application requirement.
Triangular Pitch
In triangular pitch, holes are arranged in staggered rows forming a triangular pattern.
Benefits of Triangular Pitch
This pattern is widely used in filtration and ventilation applications.
Square Pitch
In square pitch, holes are arranged in straight horizontal and vertical lines.
Benefits of Square Pitch
Open area refers to the percentage of a sheet occupied by holes. For instance, if a perforated sheet has an open area of 30%, it indicates that 30% of the sheet consists of holes, while the remaining 70% is solid material.
Higher open area provides:
Lower open area provides:
A proper balance between open area and strength is important while selecting perforated sheets.
In addition to the open area, several other factors should also be considered while selecting a perforated sheet, such as hole arrangement, straight-line hole patterns, staggered hole patterns, hole orientations at 45° and 60° patterns. Refer to the images for a better understanding of these configurations and their impact on performance and appearance.
45 Degree Staggered Hole Pattern: In a 45-degree pattern, the holes are arranged diagonally. This pattern provides balanced strength and good appearance.

60 Degree Staggered Hole Pattern (Triangular Pattern):A 60-degree perforation pattern is also known as a triangular pitch pattern. In this pattern, holes are staggered at 60 degrees.
This pattern provides maximum open area and better airflow compared to straight patterns.

Staggered Line Holes: In staggered perforation, each row of holes is offset from the previous row.

Straight Line Holes: In straight line perforation, holes are aligned directly in horizontal and vertical rows.

Sheet thickness should be selected according to the load, pressure, and application requirements.

Round hole perforated sheets are the most widely used type due to their excellent strength, uniform airflow, and versatility. Manufactured using precision CNC punching, they ensure consistent hole size and distribution, making them ideal for filtration, ventilation, and protective screening across industries like pharmaceuticals, food processing, and construction.
These sheets offer high load-bearing capacity with optimal open area, ensuring efficiency and durability.
Available in stainless steel, mild steel, and aluminium, they can be fully customized, cost-effective, and reliable solutions for bulk orders with long-term performance.
Square hole perforated sheets are designed for applications requiring higher open area and accurate material separation. Their structure allows better visibility and efficient screening, making them suitable for industries like mining, agriculture, etc.
These sheets minimize clogging and improve productivity in bulk processing operations. Manufactured with precision, they are available in various materials and customizable sizes to meet industrial requirements.
Our top-quality square perforated sheets offer durability, performance, and competitive pricing for large-scale applications.
Capsule-shaped or slotted perforated sheets are ideal for applications that require directional flow and precise filtration. Their elongated slot design enables higher flow rates while maintaining filtration accuracy, making them suitable for water treatment, oil filtration, and chemical processing industries.
These sheets reduce pressure drop and enhance operational efficiency in screening and separation systems. They can be customized in slot size, orientation, and material to match specific industrial needs.
Our capsule-shaped perforated sheets offer a high-performance, reliable solution for bulk orders in specialized and demanding applications.
Stainless steel perforated sheets are a preferred choice for industries that demand high corrosion resistance, durability, and long-term performance. Manufactured using advanced CNC punching technology, these sheets ensure precise hole patterns, consistent quality, and superior strength.
They are widely used in filtration systems, chemical processing, pharmaceutical manufacturing, food processing, and architectural applications where hygiene and reliability are critical.
Mild steel perforated sheets are a cost-effective and versatile solution for a wide range of general industrial applications. Known for their strength and ease of fabrication, these sheets are widely used in screening, safety guards, machine enclosures, partitions, and structural components across industries like construction, engineering, and manufacturing. They are manufactured using precision punching to ensure uniform hole patterns and consistent performance.
Aluminium perforated sheets are lightweight, corrosion resistant, and commonly used in architectural applications, ventilation systems, and decorative panels.
These sheets are widely preferred for applications where lightweight structure, corrosion resistance, and aesthetic appeal are essential. These sheets are manufactured with precision punching to ensure uniform hole patterns, making them ideal for architectural facades, decorative panels, ceiling systems, and ventilation solutions.
Their excellent resistance to moisture and environmental exposure makes them suitable for both indoor and outdoor use.
