Steel plate

Steel plate

Steel plates are flat structural materials thicker than 6 mm, available in carbon, alloy, stainless, abrasion-resistant and weathering grades—offering strength, corrosion resistance, wear resistance, and suitability for industrial, construction, and pressure vessel use.

FAQ

Steel plates are flat, rectangular sections of steel with a large width-to-thickness ratio, used in construction, manufacturing, energy, transportation, and more.

They include thin-sheet plates (<6 mm) and thick plates (up to 150 mm+), further categorized by material such as low-carbon, alloy, abrasion-resistant (e.g., AR235, AR400, AR500), and quenched & tempered (e.g., T1).

Common grades include:
  • A36: general-purpose structural, weldable and formable.
  • A572-50: low-alloy, higher strength (~50 ksi yield).
  • AR400, AR500: abrasion-resistant with 360–500 HB hardness.
  • T1: quenched‑and‑tempered alloy with high strength (~3× A36).

Uses include:
  • Construction – foundations, bridges, structural supports.
  • Manufacturing – vehicle chassis, machinery, ship hulls.
  • Energy – storage tanks, pipelines.
  • Material handling – chutes, hoppers in mining and agriculture.

Consider:
  • Material properties: strength, weldability, formability, hardness.
  • Application needs: load, environment, abrasion, corrosion.
  • Grade selection: A36 for general use, AR grades for wear, alloy grades for strength.

Store in dry, ventilated areas on pallets or racks. Apply rust-inhibiting coatings or sealants if needed.

Labels should include heat number, grade, dimensions, mechanical properties, and chemical analysis for traceability and quality control.

Steel plate refers to flat sections cut from rolled stock. Structural steel refers to shapes like I-beams or channels for building frameworks

Benefits include cost-effectiveness, ease of fabrication, design flexibility, fire and mold resistance, and reusability

Industrial Applications

Steel plates are vital across industries for their exceptional strength, durability, and processing versatility.

Construction & Infrastructure

Used in bridges, high‑rise buildings, tunnels, and prefabricated homes for structural frames, foundations, and decks.

Shipbuilding & Marine

Essential for hulls, decks, offshore platforms, and equipment exposed to harsh marine environments.

Automotive & Transport

Used in vehicle frames, chassis, body panels, and defense vehicles for impact resistance and strength.

Energy & Oil‑Gas

Fabricates pipelines, storage tanks, pressure vessels, wind towers, and boiler supports.

Manufacturing & Machinery

Used in heavy machinery bases, wear‑resistant liners, industrial tools, and equipment.

Defense & Military

Military-grade plates for armored vehicles, warships, and ballistic protection.
