Detailed Description
Perforated Metals are made by high speed feed and punching machines. Ours are purpose built and amongst the fastest and most accurate in the industry. Used extensively in the architectural, engineering, building, agricultural, nuclear power, food processing, and petrochemical industries.It can be made in a range of round, square, slotted or Hexagon patterns. The round hole perforation is the most popular type of perforated pattern used and is manufactured in coils or sheets. We have a full and comprehensive finishing service for all of our materials including cutting, annealing, slitting, forming, bending with a return or radiused and welding. Cut pieces of mesh can be made to your specific requirements.
Perforated Metal Material :
We can offer the following Stainless steel perforated metal ,Carbon.steel,,Galvanized steel perforated metal,Aluminum perforated metal,Brass,ect.
The hole shap :
Round, Square, Long round, Triangle ,Scale ,Diamond, and Oval etc.
Perforated Metal Aperture:
In general it is advisable to use a hole size larger than the material thickness. The closer the hole size and material thickness come to a 1 to 1 ratio, the more difficult and expensive the process is. Dependent on the material type, smaller hole size to material ratios can be achieved. Contact your Sales Representative to discuss your special requirements.The minimum diameter that we can fabricate is 0.003" (0.08mm) .If you require a die that isn't already in our die bank, our experienced tool and die makers can quickly make exactly what you need at a reasonable cost.
Pattern :
We have tooling available for many different hole patterns and shapes.
〈1〉、60° taggered
60 Degree Staggered Centers are the most popular of all pattern types because of their inherent strength, their multitude of varied open areas, and their attractive appearance
〈2〉、45° Staggered
An alternate to the traditional 60 degree staggered centers patterns. 45 degree patterns are an option for those looking for something different.
〈3〉、Straight
A popular arrangement, straight center round hole patterns are available in multitude of sizes and open areas. They are however, the weakest of the round hole patterns.
〈4〉、Square
Square patterns provide some of the highest percent open area but are relatively low in strength, thus making them ideal for application requiring good visibility and through-put such as guards.
〈5〉、Round - slot staggered
Round - slot, side staggered patterns are ideal for sorting and grading solids that flow over the width dimension of the material - so not to miss any of the holes.
〈6〉、Round - slot, straight
Round - slot, straight patterns are ideal for sorting and gradingsolids when used in a shaking application.
〈7〉、Hexagon patterns
Ideal for uses where maximum through-put is needed, hexagon patterns provide the highest open area of all pattern types.
Hole center :
Hole center is the distance from the center of one hole to the center of the nearest hole in the next adjoining row.
Specification :
We can manufacture a wide rang of thick sheet verifying from 0.1mm to 25mm Length is the overall measurement of the long side of the sheet.Width is the overall measurement of the short side of the sheet.The srandard sheet size is 1000mmX2000mm.and1000mmX2500mm.The coil width 1000mm is also available.We also can process the special product for your requirement if you tell us the exact specification.
Open area :
Obviously a hole size and hole pattern has to be chosen that meets the open area requirement of the application.Open area is the total area of the holes divided by the total area of the sheet and is expressed as a percent .Keep in mind that punching holes in a material add stresses that can result in distortion of the product. The higher the open area, the more material distortion takes place, especially when the perforated pattern is bordered by margins on all four sides.
Margins :
Margins are the blank area along the edges of the sheet.The standard sheet is the minimum margins along the length and no margins along the width.
End patterns :
A finished end pattern is often more expensive than an unfinished end pattern . If not specified, unfinished end patterns will be offered.
Tolerances :
There are tolerances on thickness ,bars,openings,flatness,and shering for perforated products.As with other manufacturing processes, tolerances tighter than the standard tolerances will result in increased cost. You should specify a specific tolerance,so we can give you a precise prudoct.If not,we will according to standard tolerance.
