McNICHOLS carries a large selection of Handrail Components that attach to stair and platform handrail systems. These include Drive-On, Slip-On and Weld-On attachment types with each having a variant of Handrail Components to choose from. McNICHOLS also provides a wide selection of product Accessories—Angles, Carrier Plates, Clips, Flat Bar (Banding), Nosing, U-Edging and more—specifically for our product offerings. Accessories complete Hole Product designs with a clean finish, minimal guesswork, and optimal long-term results.


The following selections are important considerations to help you choose the right McNICHOLS® Perforated Metal product for your project or application. Please specify:



Product applications/uses include displays, exhibits, fixtures, partitions, cabinet inserts, guards, furniture, building facades, infill panels, screening, sign panels, filters, baskets, ventilation, security enclosures, and more. We invite you to browse Perforated Metal applications in our Product Gallery.


Hole Type

Choose from a wide variety of Round, Square, Slotted, Hexagonal, or Designer Perforated hole types.


Primary Material / Product Finish

Select primary material type including Aluminum, Carbon Steel, Galvanized Steel, Stainless Steel, or Plastic, taking into consideration climate or environmental realities. Inventory is typically “mill finish” unless otherwise specified. We provide our full selection of materials in the Materials, Finishes, Gauges/Thicknesses section.


Material Gauge / Thickness

Decide on material gauge number or thickness in inches. The Gauges and Weights Chart offers additional information.


Hole Pattern

Identify hole size (diameter), hole type (shape), hole center (spacing) and hole arrangement (staggered, straight row, etc.), or Designer Perforated name/pattern.


Percent Open Area

Choose the percentage of open area desired in the Perforated Metal sheet or coil.


Margin / End Pattern

Specify solid margin preferences on width and/or length of sheet if required for your application. Most inventory 11 Gauge and lighter has minimum solid side margins running the length of the sheet and no end margins running the width of the sheet (material ends are sheared through). Sheets heavier than 11 Gauge typically have either a finished or unfinished pattern with corresponding end margins.


Product Size, Form & Quantity

Identify product size(s), form (typically supplied in sheets), and quantity desired, including cut-to-size pieces.


Special Requirements

Specify any requirements for special cut-to-size pieces, margin or edge treatments, finishing, leveling, fabrication, non-standard tolerances, etc.



Determine if Perforated Metal Accessories such as Angle, Flat Bar or U-Edging framing solutions are required for your application.
