When you need JIS SS400 steel plate for structural fabrication, machinery frames, construction parts, welded components or project supply, send grade, thickness, width, length, quantity, processing requirement, MTC requirement and destination. We can support SS400 and related JIS general structural steel plate grades according to confirmed specification, production feasibility and project requirement.
This page focuses on SS400 steel plate. SS400 is commonly requested in JIS structural steel inquiries for general fabrication, construction parts, machinery frames, welded components and distributor stock supply. If your drawing specifies SS400, quote SS400 directly instead of replacing it only by similar strength or application.
If your purchasing document uses SS400, send the required thickness, width, length, quantity, cutting size, destination and document requirement together. We can review SS400 steel plate supply, production arrangement, cutting, inspection, packing and export shipment according to your order details.
You can send cutting drawings, plate size, hole position, beveling details, tolerance and plate marking needs before quotation.
You can confirm SS400 according to the drawing, JIS material requirement, project acceptance and MTC requirement.
You can request common plate sizes, mixed thickness orders, export packing, shipping marks and loading records for resale or repeat supply.
SS400 is the main product of this page. Related JIS G3101 general structural steel plate grades can also be reviewed according to confirmed grade, thickness, width, length, quantity, testing requirement and mill availability.
Main grade for general structural fabrication and steel component supply.
Related general structural steel grades can be reviewed if your project or buyer specifies them.
Do not send only “mild steel plate” if the drawing requires SS400. Exact grade wording affects quotation and MTC.
A36, Q235 and S235JR can be compared only when your buyer or project documents allow another standard route.
SS400 quotation depends on grade wording, plate size, quantity, surface condition, processing method, inspection requirement and destination. Clear RFQ details help reduce repeated communication before quotation.
SS400 is commonly used for general structural steel applications. The final plate size, processing method and document requirement should match your drawing, fabrication plan and buyer acceptance rules.

You can discuss flame cutting, plasma cutting, laser cutting or fixed-size plate cutting according to your drawing.
You can send hole position, beveling requirement, plate marking and drawing details before quotation.
You can align material certificate, heat number, plate marking, grade, size and order details before delivery.
You can request steel straps, wooden supports, labels, shipping marks, packing photos and loading photos.
You can match SS400 plate with fabrication, construction steel structures, machinery frames or project steel supply.
Buyers often compare SS400 with ASTM A36, Q235 and S235JR in general structural steel plate inquiries. These materials are not automatic equivalents. Final selection should follow project drawings, local standard, MTC and buyer approval.
