Versatile Perforated Metals for serving industries

Heanjia Super-Metals produce perforated sheet and screen products that are utilized in abundant of applications including sound abatement, grills, screens, HVAC duct liners, acoustic ceiling and architecture accents. Our numerous in-house tools and multiple die punches, single punch, CNC, laser cutting and plasma CNC capabilities empower us to deliver any perforated metal shape and pattern. We take pride in offering experience of years, knowledge and unrivaled perforation services to our valuable customers. We supply the quality products that meet our customer’s requirements.

Benefits of Perforated Metal

There are several diverse techniques to perforate a metal, nothing is better than the dedicated perforating process that offers the most lucrative and high quality result. Advanced high speed CNC presses can develop holes at the large rate such as about 1,000,000 per minute. Our presses are programmed with your specific requirements to offer exclusive solutions. Imperatively, we can develop the perforated designs with the specific blank areas, special margins, variable spacing of holes and position of locator holes, everything at the extremely tight tolerances.

Heanjia Super-Metals have the flexibility to produce the perforated metal sheet using the various materials and in the thickness ranging foil to thick plate. We produce the perforated sheets in sizes about 60 inches and coils of weight 20,000 lbs, suitably rewound. The tools are available in-house for custom hole patterns such as square, round, triangle and rectangle an slots with minimum width about 1/64 inch.

To meet your perforation needs, professional leveling is done. Our in-house leveling removes distortions, burr and oil. It is an imperative process to obtain the ultra tight tolerances in the punching process and to confirm the quality finished component.

Post-perforation operations include cutting, bending, welding, painting and plating. Eventually, we are your perforating expert for your entire perforating requirements.

Functional capability

With the perforating metal, there are several factors to consider in addition of price. Several applications include a product designer or architect to offer a material that has perforated area to allow flow of air, liquids or sound or in fact solids for food processing equipments. The selection of material for these applications usually comes to perforated metal.

The base factors of choice are price and quality, undoubtedly, however there are also other essential factors to take into consideration. The required function of material is also essential. There are some functions that can only be done by perforated metal.

You may wonder at few of the less common capabilities of the perforated metal in the sound managing devices that exceed becoming transparent to sound to permit to travel through absorbing materials. Perforated metal also has a significant role in systems that remove the particular sound frequencies as those occurred in jet engine nacelles and enclosures that cover large size air conditioner or compressor. The Perforated sheet is extensively used to keep diverse types of radiation whilst providing air and light flow. For example, Microwave oven.

Many common functions of Perforated metal are listed following. Several hole shapes, sizes and patterns are offered to designers and architects to deliver more choices and excellent solutions for their design projects. There are many conditions when you will observe that perforated metal performs equal to expanded metal and woven wire cloth. So it is not just the matter of cost.
