MKM Muammer Kagitcioglu | Perforated sheet and expanded metal

Tracing its origins back to 1938, Muammer Kagitcioglu Makine Sanayi ve Ticaret A.S. combines extensive industrial heritage with modern sheet metal fabrication technologies. Based in the Cigli Organized Industrial Zone in Izmir, Turkey, the company operates dedicated production lines providing tailored metal forming and perforation solutions under its specialized brand, “Izmir Delikli Sac”. Evolving from an artisan workshop over four decades into an advanced industrial facility, the enterprise consolidates raw material processing, cutting, perforating, expanded mesh production, and finished assembly under a single roof.

### Perforated Metal Manufacturing

The company’s perforated sheet production operates in accordance with DIN 24041 geometric patterns, backed by an internal archive of over 1,000 punch and pitch tooling combinations. Engineering calculations ensure exact open area percentages and structural integrity across various materials, including cold-rolled steel (DKP), mild black steel, galvanized sheet, stainless steel, aluminum, and copper. Sheet dimensions range from standard A4 sizes up to 1,700 mm x 5,000 mm, with minimum hole diameters starting at 1.2 mm. Specialized patterns include:

• Round hole sheets: Offered in 60° staggered (Rv) formations for maximum ventilation and uniform load distribution, as well as straight pitch (Rg) alignments for parallel visual continuity.
• Square hole sheets: Qg patterns engineered for elevated free-flow ratios, ideal for screening plants, sorting systems, and machine ventilation guards.
• Slot and oval hole sheets: Long-aperture Lv and Lg layouts configured to enhance the drainage of liquids and the separation of bulk grains in agricultural machinery.
• Decorative perforations: Custom aesthetic patterns developed for architectural facade cladding, interior feature walls, furniture, and designer lighting.
• Embossed and countersunk perforations: Raised-hole patterns delivering slip-resistant traction on industrial walkways, work platforms, transport loading docks, and inner drums of industrial laundry equipment.
• Heavy-duty screen plates: Thick, wear-resistant steel plates engineered for rigorous sorting in aggregate processing, coal handling, and quarrying operations.
• Acoustic and filtration meshes: Finely perforated panels for sound-absorbing wall and ceiling linings, alongside high-density micro-perforated sheets for liquid strainers and gas filter assemblies.

Unperforated margins, custom border dimensions, and project-specific edge contours are fully integrated based on architectural or mechanical drawings.

### Expanded Metal and Architectural Systems

Manufactured by slitting and stretching sheet metal without material waste, expanded metal solutions offer exceptional strength-to-weight performance. Standard raised-mesh profiles create rigid, slip-resistant decking for cat walks, stair treads, and safety barriers. Flattened (rolled) mesh provides a smooth, leveled finish suitable for retail display shelving, perimeter enclosures, and architectural skins. The facility also fabricates exterior sunscreens, facade cladding envelopes, balcony and balustrade panels, and acoustic sound barrier panels engineered for highways and rail infrastructure.

### Comprehensive Fabrication and Engineering Services

Beyond perforation, the Izmir production plant provides turnkey contract manufacturing and structural steel engineering:

• Thermal and mechanical cutting: Capabilities include CNC guillotine shearing, high-precision laser cutting, plasma cutting, and oxy-fuel cutting for heavy gauges.
• Forming and presswork: Hydraulic press brake bending, mechanical punching, deep pressing, and general machining for tight-tolerance components.
• Welded steel construction: Design, 3D structural modeling, and certified welding for industrial project-based assemblies ranging from 5 mm to 150 mm in material thickness.
• Surface treatment and coating: In-house chemical pre-treatment, protective coating, electrostatic powder coating, and liquid wet painting lines ensure durable protection against atmospheric corrosion.

### Quality Assurance and Operational Workflow

Manufacturing processes comply with certified international management standards, including ISO 9001:2008 for quality management, ISO 14001:2004 for environmental management, ISO 10002:2004 for customer satisfaction, TS EN ISO 3834-2:2007 for fusion welding requirements, and OHSAS 18001:2007 for occupational safety. The four-stage delivery model begins with engineering consultation on open area and material selection, proceeds to 3D design approval, moves through CNC-monitored fabrication with batch dimensional verification, and concludes with secure surface-protective packaging for domestic and international freight delivery.
