JIS SS490 Steel Plate Sizes: Thickness, Width and Length Guide

Selecting the correct dimensions is an essential part of purchasing JIS SS490 steel plate. For construction companies, steel fabricators, and international distributors, accurate size information helps control material costs, reduce cutting waste, and simplify transportation planning.

Thickness is usually the first specification to confirm. The required thickness depends on the component design, applied loads, fabrication requirements, and applicable engineering standards. Buyers should follow the approved drawings rather than choosing a thickness based only on general application examples.

Width and length determine how efficiently the plate can be used during fabrication. Larger plates may reduce the number of individual pieces or joints required, while smaller plates may be easier to handle and transport. The best dimensions depend on the finished component sizes, available cutting equipment, and project layout.

When requesting a quotation, buyers should provide dimensions in a consistent format, such as thickness × width × length. For example, a requirement might be written as 12 mm × 2,000 mm × 6,000 mm. The buyer should then state the number of plates or required total tonnage. This example is for illustrating the format, not a guarantee of stock availability.

It is also important to distinguish between standard stock sizes and custom sizes. A supplier may have certain dimensions available for immediate shipment, while other sizes may require new production or cutting from larger plates. Buyers should confirm availability and dimensional tolerances before placing an order.

For bulk purchases, accurate dimensions help suppliers calculate theoretical weight and prepare quotations. If cutting or other processing is required, the finished dimensions and acceptable tolerances should be stated separately.

Before purchasing SS490 steel plate, confirm the JIS standard, thickness, width, length, quantity, certification requirements, and delivery destination. Providing complete specifications makes quotations easier to compare and helps prevent costly misunderstandings during procurement.
