Banding A process involving the application of a flat piece of metal to the end of cut bar grating to give a more finished appearance and protect the ends.

Bevel Cutting A type of cut where the blade is set to other than a 90 degree angle with respect to the surface of the material.

Circle Cutting Shearing or sawing material in a circular path to a specified dimension.

Coating A material applied as a covering to another material such as vinyl coating applied to steel.

Cut to Size This describes the option of cutting a standard size into pieces of specified size with typically 90 degree corners. Used to describe this process regardless of what tool or machine is used to do the cutting.

Drawings Required Drawings required to confirm material specifications, sizes or to aid in erection of the finished materials.

Hot Dip Galvanizing The process of applying a zinc rich coating to steel to prevent corrosion by submerging the material in a tank of molten zinc for a period of time.

Install Mounting Lugs The process in which flat pieces of material are fit and welded in place between bearing bars on grating to facilitate the attachment of the grating to its structure.

Install Nosing The process by which a nosing product is added to the leading edge of a piece of grating or a stair tread.

Install Toe Plate The process by which a flat piece of material is attached to the edge of a piece of grating at a 90 degree angle to the surface and extending above the surface of the material, preventing a foot from extending over the edge of the grating

Notching A type of cutting where material is removed from a portion of the edge of a product to specified dimensions resulting in a "cut-out" or notch in the edge of the material

Pressure Blasting Pressure blasting consists of attacking the surface of a material with one of many types of media. Sand, glass and shot blasting are most common. Can be used to remove rust or corrosion or to impart a different surface finish to the material.

Welding The process of fusing two pieces of metal together through the application of heat, sometimes with pressure and sometimes with an intermediate or filler material having a high melting point.
