Structure
This section defines the design and specification requirements for adjustable metal shelving racks categorized into open, semi-open, and closed types. It references relevant Indian Standards for materials such as structural steel (IS 2062), rolled steel sections (IS 808), bolts and nuts (IS 1363, IS 1364), surface treatments (IS 2633, IS 4736), and wood-based panels (IS 1659, IS 303). It also stipulates rounding off rules for test or calculated values as per IS 2-1960 and outlines the purchaser's responsibility to provide technical data when ordering.
Details the approved materials for various components of shelving racks including structural steel (IS 226), rolled steel sections (IS 808), cold-rolled carbon steel strips (IS 513), black square and hex bolts and nuts (IS 1363, IS 1367), zinc electroplated and hot-dip galvanized coatings (IS 2629, IS 4759), and mild steel sheets (IS 1079/IS 513). It emphasizes compliance with rounding off values as per IS 2-1960.
Specifies nominal overall dimensions for shelving racks with heights from 975 mm to 4875 mm in 300 mm increments and shelf depths of 300, 400, 500, and 600 mm. It defines ground clearance at 45 mm and minimum clearance requirements for recessed racks: 20 mm at the top, 10 mm at each side, and 5 mm in depth. Metal shelves must be fabricated from mild steel sheets of at least 1.0 mm thickness with lipped flanges measuring 30 mm wide and 15 mm deep.
Outlines the nominal dimensions and allowable deviations, specifying that all measurements may vary by ±5 mm. It reiterates the clearance requirements for installation in recesses and defines closed-type racks as those equipped with side and back panels.
Describes the material grade requirements for angles and sheet metal parts and mandates assembly exclusively through bolted connections. Bolts and nuts must conform to relevant IS standards to ensure strength and proper fit. It also specifies secure packing of all components to prevent damage during transportation.
Focuses on assembly using bolting methods with minimum bolt size M6. Bolts and nuts must adhere to Indian Standards IS 2585-1968 for square bolts and IS 1363-1967 for hexagonal nuts. Fasteners should be zinc plated or galvanized in accordance with IS 1573-1970 or IS 5358-1969. The section also covers the secure packaging requirements for shipment.
Details surface preparation steps including pickling to remove imperfections, phosphating according to IS 3618-1966 and IS 6005-1970, and application of putty conforming to IS 110-1968. Aluminium primer per IS 5660-1970 is applied prior to painting. Paint and enamel finish colors are agreed upon between purchaser and manufacturer. Performance tests for flexibility and adhesion are conducted per IS 101-1964 to ensure coating durability.
Specifies testing for pressure resistance and flexibility/adhesion of paint coatings using mild steel samples of defined size and thickness following IS 101:1964 clauses. Acceptance criteria include no visible metal exposure after pressure testing and absence of cracking or detachment under magnification for adhesion tests. All results must be rounded according to IS 2:1960.
States the maximum static uniform load permitted per shelf as 150 kg. Provides dimensional ranges for shelves and clearance requirements. Highlights the use of reinforcements such as shelf braces and side supports to safely accommodate loads.
Lists the details purchasers must submit when ordering including number and type of racks, rack dimensions, number of shelves, partition details (number, height, and location), accessory requirements such as binstrips and label holders with dimensions, color specifications, and strip requirements for open racks. Also notes the requirement for manufacturer marking on all racks.
Covers manufacturer identification marking mandatory for all racks and optional use of the BIS Standard Mark subject to licensing under BIS regulations. Emphasizes adherence to rounding off rules and purchaser order specifications to ensure traceability and compliance with the standard.
Frequently Asked
According to the standard, each shelf in adjustable metal shelving racks can safely support a maximum static uniformly distributed load of 150 kg. Shelves must be constructed from mild steel sheets with a thickness of at least 1.0 mm and feature lipped flanges measuring 30 mm in width and 15 mm in depth. This load limit serves as a guideline to ensure safe usage under standard conditions.
The standard approves various materials including wood-based panels such as particle boards, veneered particle boards, blockboards, and plywood for shelves and backs, with minimum thicknesses of 20 mm for shelves and 10 mm for backs. Metal shelves and sides are to be made from mild steel sheets with minimum thicknesses of 1.0 mm and 0.8 mm respectively. Supporting brackets for wood shelves must be mild steel of at least 1.6 mm thickness featuring 8 mm diameter holes.
Corrosion resistance is assessed using a mild steel panel (150 mm x 100 mm x 1.25 mm) finished per the standard's surface treatment procedures and subjected to condensation tests as described in IS 101:1964, Clause 18, with acceptance criteria requiring no visible corrosion. Paint adhesion is verified through standardized tests such as cross-cut or tape tests to ensure no peeling or flaking occurs, guaranteeing the durability of the coating.
Shelving racks have nominal heights ranging from 975 mm to 4875 mm in increments of 300 mm, and shelf depths of 300, 400, 500, or 600 mm. Ground clearance is set at 45 mm. Minimum installation clearances include 20 mm at the top, 10 mm at each side, and 5 mm in depth. All dimensions have a permissible tolerance of ±5 mm. Metal shelves are made from mild steel sheets of at least 1.0 mm thickness and equipped with lipped flanges 30 mm wide and 15 mm deep.
Purchasers need to specify the quantity of racks, the type (open, semi-open, or closed), rack size per dimensional guidelines, number of shelves, partition details (including number, height, and placement), accessory requirements such as binstrips and label holders with their widths, color preferences, and for open racks, the number and placement of strips. Additionally, racks must bear the manufacturer's identification mark for traceability.
