Decorative Holes offer you design options with a wide array of hole shapes, gauges and materials in straight and staggered patterns. Others are available by special order. You may narrow your selection choices by using the left navigation pane or browse our stock list below.
How is Decorative Perforated Made?
Decorative perforated is a sheet or coil of material made from metal that contains holes punched by a die. The shape of the hole is determined by the shape of the die. For perforated with a decorative hole pattern, the die is shaped in various forms. Common, in-stock sheet sizes for perforated decorative hole products include:
· 48 x 120 inches
· 48 x 96 inches
· 36 x 120 inches
· 36 x 96 inches
The uses for decorative perforated metal are endless. Many customers use decorative metal to make cabinets, wineries, backgrounds, walls, baskets, furniture, etc. There are numerous kinds of decorative types to choose from. See the navigational column to the left to see the details for each pattern.
Thickness is the measurement from the top surface to bottom surface of the material. Gauge is the most common measurement, but thickness can also be measured in fractional inches or millimeters. This gauges and weights chart can provide additional information.
Perforated sheets contain holes and material. Open area is the total area of the holes divided by the total area of the sheet and is expressed as a percent. In other words, open area describes how much of a sheet is occupied by holes. If a perforated sheet has 60 percent open area, then 60 percent of the sheet is holes and 40 percent is material. .
Because of the complex shape of the decorative holes pattern design, calculating the open area is difficult. This information is provided in the in-stock and special order decorative sections.
Note: Specify either Open Area or Centers, but not both.
Length is the overall measurement of the long side of the sheet; width is the overall measurement of the short side of the sheet. Note that mill tolerances for length and width apply to stock sheets unless otherwise specified. If you have a stock sheet cut-to-size, cut tolerances apply. To specify other than standard tolerances, please use the perforated round hole pattern quote form to specify the required tolerances.
Quantity is the number of full sheets or cut pieces you need. Unless otherwise specified, the standard tolerance on quantity is ’Exact Quantity’. In other words, McNICHOLS will deliver the exact quantity you specify.
Margins are the blank (unperforated) area along the edges of the sheet. For stock sheets, the standard is minimum margins along the length and no margins along the width.
To specify other than standard margins, use the perforated round hole pattern quote form. Provide the width of each margin on all four sides (measured from the edge of the sheet to the edge of the first hole) and the direction to which the margin is parallel (side or length dimension). Manufacturing considerations may affect margins. If the margins requested are not possible, the quote you receive will specify the new margins.
Below is an example of a margin specification based on the illustration to the right:
Margins:
· 0.25 inch margins parallel to both 24.75 inch dimensions
· 0.375 inch margins parallel to both 48 inch dimensions
There are tolerances on quantity, shearing, circle shearing, flatness, thickness, and squareness for perforated products. If you do not specify a specific tolerance, the standard tolerance applies. Tolerances can be specified on the perforated round hole pattern quote form.
