Service consulation:we guarantee to give you the better service for any dealing with us.if you are not familiar with our sevice,no matter it is the design,price,plan or the technique and the delivery line,we have professional person to serve for you.we guarantee to do our best to resolve the matter until to your satisfaction.We provide a brief guide to help you understand the nomenclature used for the specification of different types of perforated sheet.
Materail:we can provide you the following material:stainless steel ,carbon sheet,galvanized,aluminium,brass,copper,plywood,fiberboard,rubberboard,woodboard,pasteboard,AL-MG alloyplate,Nichel-plate,PVC plate and others composite.
Specification:we can manufacture a wide rang of sheet thickness from 0.1mm to 25mm.Length is the overall measurement of the long side of the sheet.The standard sheet size is 1000mm*2000mm,1250mm*2500mm,The coil width 1000mm is also available.We also can produce the special specification according your requirement.
The hole shape:round,square,triangle,scale,diamond,oval,hexagular,slot etc.
Pattern:we have tool available for many different hole patterns and shapes.It is more economical to choose one of the available patterns,although special hole sizes and patterns can be accommodated at additional cost.
Pitch:pitch is the distance from the center of one hole to the center of the nearest hole in the next adjoining row.
Open area: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.but these distortions can be removed by our special in house leveling process.
Margins:margins are the blank area along the edges of the sheet.if you want the product with special margins,you should provide the width of each margin on all four sides£¨measured from the edge of the sheet to the edge of the first hole£©.manfacturing considerations may affect margins.if the margins requested are not possible.we will replace it with the similar products as your consideration.
Tolerances:there are tolerances on thickness,pitch,opening,flatness and shearing for perforated products,you should specify a specific tolerance,so that we can supply you a perfect product.if not,we will according to the standard tolerance.
Hole of shape and arrange style: The round is the most widely used design of section.It's arrange style divide into two kinds:
