  • If grating surface deflection should be considered when selecting a product to meet a particular specification, then the deflection of the mid-width of the grating, relative to the side channels, can be calculated using both the data in the strut loading tables (pages 8 -19) and the load/deflection conversion formula on top of following page . SECTION 05 51 00 - METAL STAIRS Subject: Master Construction Specifications Keywords: Metal stairs, stairs, steel stairs, railings, industrial stairs, closed riser stairs, riser stairs, steel pipe, steel grating, sheet steel, structural steel, steel floor plate, steel decking, iron casting, casting, fabrication, stair Last modified by Specifications, Types and Requirements for Metal Open Bar Grating. Metal open bar grating, also called steel grating, steel bar grating, is a type of solid grating widely used in the industrial applications as flooring and stair treads. It has anti-corrosion material, multi-type and anti-slip surface to help secure workers safe and reduce Bar grating stair treads are fabricated from bar grating panels. End plates with bolt holes can be welded to the ends of the stair treads. Checker plate nosing is welded to the leading edge of the bar grating stair tread. This nosing provides increased slip resistance. Direct Metals offers nosing types in checker plate, cast abrasive or Pacific Stair Corporation's 600 Series Grating Stair System is commonly used in mechanical areas such as machine rooms, as well as exterior locations such as roof stairs. Bar Grating stairs provide a slip-resistant walking surface. Our standard design includes checker plate nosing. Manufactured to match the full line of our grating, there is an AMICO-Klemp® stair tread to meet your needs. AMICO-Klemp® stair treads are safe, self-cleaning, skid-resistant and economical. Steel and aluminum stair treads are available in a variety of styles: welded, riveted, press-locked, swage-locked and Duo-Grip™ extruded aluminum.

Steel grating stair treads are available in type “W” welded, type “SL” swage locked, or type “DT” dovetail pressure locked grating. Carrier plates are recommended for use with 19, 15, and 11 spaced gratings, while carrier angles are recommended for use with 8 and 7 spaced gratings. Types of Bar Grating Stair Treads. Steel Stair Treads. Steel grating stair treads are available in type “W” welded, type “SL” swage locked, or type “DT” dovetail pressure locked grating. Carrier plates are recommended for use with 19, 15, and 11 spaced gratings, while carrier angles are recommended for use with 8 and 7 spaced gratings. Stair Treads: Stair treads shall be designed for a uniform load of 100 psf (4.79 kN/m2) per ASCE 7 or a concentrated load of 300 lbs (1.33 kN) on an area of 4 sq. inches (2580.6 mm²) located in the center of the tread, whichever produces greater stress and deflect less than 0.25” (6.4 mm). The two loads do not act concurrently. Pacific Stair Corporation's 600 Series Grating Stair System is commonly used in mechanical areas such as machine rooms, as well as exterior locations such as roof stairs. Bar Grating stairs provide a slip-resistant walking surface. Our standard design includes checker plate nosing.

  • Common Specifications and Types of Steel Grating for Stair Treads

    Length of steel grating stair treads Common length. 700 mm, 800 mm and 900 mm are the most widely used and popular width. Maximum length is 1200 mm. If there are several people passing at the same time in double direction or it is used as the escape line for workers, the stair tread width should choose 1200 mm.;Common Specifications. Popular Material: Material: low carbon steel, stainless steel 304, 316, etc. Surface treatment: galvanized, painted. stair treads can be made of any kind of steel grating. Can be divided into 4 basic groups: Turn floor plate down to form nosing on treads and edge of platform at head of stairs. 2. Support tread and platforms with angles welded to plate. 3. Do not leave exposed fasteners on top of treads or platform surfaces. 4. Provide flat sheet steel risers for stairs with steel plate treads where shown. Common Specifications. Popular Material: Material: low carbon steel, stainless steel 304, 316, etc. Surface treatment: galvanized, painted. stair treads can be made of any kind of steel grating. Can be divided into 4 basic groups: Install Perf Safety Grating and Perf Safety Grating 2 stair treads as shown on the drawings. Fasten treads to stair stringers with 3/8” x 1” machine bolts and nuts. a. For stair treads, intermediate stringer is recommended for spans over 4 feet. Steel Grating Specification Steel grating is commonly made of flat steel panel and supporting bars welded together with setting spacings. It goes through cutting, opening, edging and other processes. The popular vertical bar grating spacing is 30mm, 40mm or 60mm, horizontal bar grating is 50mm or 100mm normally. Common Specifications.
