Structural carbon-steel plate for base plates, gussets and fabricated parts
We supply ASTM A36 steel plate for structural fabrication and distributor material orders. Each line identifies thickness, finished dimensions and quantity. Cut blanks retain their parent-plate and heat reference, with edge preparation and required examination itemized in the supplied work.
| Material requirement | ASTM A36/A36M with the required edition and additional requirements |
|---|---|
| Dimensions | Thickness × width × length, or released part drawing |
| Product route | Mill plate or qualified coil-derived plate identified where relevant |
| Surface and edges | Mill condition or specified cut-edge preparation |
| Testing | Material test record and ordered supplementary examination |
| Traceability | Heat/plate cross-reference retained through the cut schedule |
These published material values help check the grade description before selecting plate dimensions.
| Property | Reference value | Reference scope |
|---|---|---|
| Minimum yield strength | 36 ksi | SSAB A36 plate reference, 0.100–6.00 in. thickness |
| Tensile strength | 58–80 ksi | Same published A36 reference scope |
| Minimum elongation in 2 in. | 21% | Published base requirement; width and A6 adjustments apply |
| Minimum elongation in 8 in. | 18% | Published base requirement; width and A6 adjustments apply |

SSAB publishes these A36 plate values for 0.100–6.00 in. thickness, using transverse tensile tests and the inch-pound basis. For plate wider than 24 in., the listed elongation minima decrease by two percentage points; ASTM A6 permits additional adjustments. This producer reference is separate from our quoted dimensions and supplied heat results.
A36 has a 36 ksi minimum-yield reference in the thickness scope above. A572 Grade 50 specifies a 50 ksi minimum within its applicable product and thickness limits. The material line retains the grade required by the drawing and its corresponding acceptance requirements.
The 21% value uses a 2 in. gauge length; the 18% value uses an 8 in. gauge length. The material report identifies that basis for comparison with the purchase requirement. The forming drawing establishes the permissible bend detail for the finished part.
An order requiring impact or ultrasonic examination names the test method, temperature where relevant and acceptance criteria. We retain that supplementary examination scope on the plate line before supply is arranged.
The drawing identifies the delivered blank and final machined dimensions. Any extra stock for machining is stated as an allowance alongside the finished dimensions.
The connection drawing locates bevels, holes and profiles. Material records establish the A36 steel identity, while dimensional inspection records the prepared features.
A cut plan links each blank or controlled group to its source plate. This preserves the material reference when several sizes come from one parent plate.
Base plates, gussets and stiffeners are ordered by their actual outlines and thicknesses. Anchors, welds and finished connection acceptance are separate from supply of the plate blank.
A36 blanks can be grouped by part mark for an assembly schedule. The material list keeps their grade and thickness separate from other structural or pressure-purpose plate items.
Material documents identify the supplied plate or controlled cut group and its actual heat. The parent-to-blank cross-reference retains that identity through preparation.
Measured dimensions use the ordered thickness basis and applicable tolerances. Finished blank width, length and squareness remain distinct from the original parent-plate dimensions.
Cutting can release residual stresses in a parent plate. The order identifies the required flatness and acceptance stage, such as after cutting or machining, so inspection checks the condition needed by the receiving workshop.
Plates and blanks are grouped by grade, thickness and part reference. Dunnage preserves lifting access and supports the package; small parts have secure identified packing.
Nominal dimensions can support a theoretical mass calculation, while the commercial basis identifies any purchased parent material, cutting yield or weighed quantity. Those are different totals.
Our offer separates A36 material, cut-part quantities, edge work and any specified tests. Packing and destination terms are included with the agreed supply scope.
The plate order states the test temperature, specimen and acceptance requirements under the applicable purchase specification. Those supplementary requirements accompany the actual material and test records.
The material certificate identifies the steel and its recorded test results. Welding uses the procedure and qualifications required for the actual fabrication and service; those records form their own part of the fabrication package.
A36 is ordered to the structural-material specification. A516 Grade 70 follows its pressure-vessel plate specification. The material schedule retains the required designation and its product, testing and certification scope.
The published SSAB reference reduces the minimum by two percentage points for plate wider than 24 in. This changes the base values from 21% to 19% in 2 in., and from 18% to 16% in 8 in., before any other applicable ASTM A6 adjustment. Acceptance uses the plate width, gauge length and ordered specification together.
Grade compliance covers the required chemistry, product, mechanical tests and certification together. A purchase calling for A572 Grade 50 needs material identified and accepted to that specification, with its full supporting records.
The quote identifies the machining work and its acceptance dimensions when supplied. A blank for later machining is delivered to its stated blank dimensions with the agreed stock allowance.
