More Details About 3/16 A36 Steel Plate

The current market quotation for this specification of steel plate is $480–$550 per metric ton, and the retail price for a single sheet (regular size: 48×96 inches) is approximately $9.5–$12 per sheet. The price is dynamically adjusted according to the procurement terms.
The core pricing factors are as follows:
  1. Purchase Volume: Wholesale price of $480–$500 per metric ton is available for bulk purchases of ≥5 metric tons; the retail price for orders under 1 metric ton will be increased by 10%–15%.
  2. Surface Treatment: The default hot-rolled pickled surface is priced at the base rate, while customized treatments like hot-dip galvanizing and painting require an additional cost of $80–$120 per metric ton.
  3. Market Fluctuation: Affected by the prices of raw materials such as iron ore and scrap steel, the short-term price fluctuation range is about ±5%. For long-term procurement, it is recommended to lock in the contract price.
  4. Additional Services: Extra fees will be incurred for value-added services such as non-standard size cutting and expedited delivery, which shall be calculated based on the specific order details.
  • Base Material Standard: ASTM A36 Carbon Structural Steel
  • Nominal Thickness: 3/16 inch (approx. 4.76 mm)
  • Thickness Tolerance: ±0.005 inch (±0.127 mm)
  • Dimension Tolerance Standard: Complies with the tolerance requirements for general structural steel plates specified in ASTM A6/A6M
  • Flatness Error: ≤1.5 mm/m
  • Surface Treatment Methods: Hot-rolled pickling (default), hot-dip galvanizing, electro-galvanizing, customized painting
  • Regular Supply Sizes:

    Width: 48–120 inches

    Length: 96–240 inches

    Non-standard size cutting customization is available

  • Implementation Standard: ASTM A36/A36M
  1. Mechanical Properties: Tensile strength ranges from 400–550 MPa, yield strength is no less than 250 MPa, and elongation is at least 20%. It features excellent impact resistance, capable of withstanding regular structural loads without easy deformation or fracture.
  2. Machinability: It boasts superior weldability and can be adapted to arc welding, gas welding and other processes without preheating. It also performs well in cold bending and stamping, and enables smooth cutting with easy precision control during machining.
  3. Weather Resistance: The hot-rolled pickled surface has basic rust prevention capability, and its corrosion resistance can be enhanced through galvanizing, painting and other processes, making it suitable for humid and mildly corrosive industrial environments.
  4. Tolerance Performance: Thickness tolerance is ±0.005 inches, and flatness error is ≤1.5mm/m. It has high dimensional stability, meeting the processing requirements of precision structural components.
  1. Construction & Structural Field: Used for manufacturing light building frames, supporting beams and curtain wall embedded parts. With stable mechanical properties, it bears building loads and is suitable for the construction of various civil and industrial buildings.
  2. Machinery Manufacturing Field: Processed into equipment bases, mechanical brackets and transmission connectors. Its excellent weldability and formability can meet the precision and strength requirements of equipment assembly.
  3. Hardware Accessories Field: Made into steel structure embedded parts, pipe fixings and hardware stampings. The moderate thickness facilitates processing, compatible with various stamping and cutting processes to reduce production costs.
  4. Maintenance & Renovation Field: Serves as replacement steel plates for equipment maintenance and load-bearing components for temporary structures, which can be quickly processed and formed for emergency repair scenarios.

Q：What gauge thickness is 3/16 steel?

A：A steel plate with a thickness of 3/16 inch has a nominal thickness of 3/16 inch. Converted to the metric system, its precise value is 4.7625 millimeters, and the approximate value of 4.76 mm (or 4.8 mm) is commonly used in the industry for daily communication and conventional processing.

In accordance with the ASTM industry standard, the thickness tolerance of this specification of steel plate is strictly controlled within ±0.005 inch (±0.127 mm), meaning the actual thickness ranges from 4.6355 mm to 4.8895 mm. This tolerance standard (ASTM A6/A6M) is suitable for the regular application scenarios of structural steel plates such as A36.
It should be noted that the nominal thickness of 4.76 mm is preferred for engineering calculations; for precision processing or quality inspection, the measured thickness and tolerance range must be strictly followed to avoid the impact of thickness deviation on structural strength and assembly accuracy.
