● ASTM A36 / A36M – Carbon structural steel
● ASTM A572 (Gr. 42, 50, 60) – High‑strength low‑alloy structural steels
● ASTM A1011 / A1018 – Hot‑rolled sheet & strip (commercial, structural, HSLA)
● BS EN 10025‑2:2004 – Non‑alloy structural steels (S235JR, S275JR, S355JR)
● DIN EN 10029 / 10051 – German/European dimensional tolerances for plates & coils
● ISO 630 – Structural steels for general purposes

● Carbon Steel Grades:
○ ASTM A36, SS400, S235JR, S275JR
● High‑Strength Low‑Alloy (HSLA):
○ ASTM A572 Gr. 50, EN S355JR/J0/J2
● Commercial Quality:
○ CQ, DQ (drawing quality)
○ DDQ (deep drawing quality)
● Custom Grades:
○ Per client specification (pipeline, shipbuilding, boiler plate, etc.)

Typical Ranges:
● Carbon %: 0.12 – 0.25
● Manganese %: 0.50 – 1.60
● Silicon: 0.10 – 0.35
● Phosphorus %: ≤ 0.035
● Sulphur %: ≤ 0.035
● Copper %: ≤ 0.35 (for atmospheric corrosion resistance)

Exact chemistry varies by grade — e.g., S355 has higher Mn and controlled C for strength + weldability.

● Coils:
○ Thickness (mm): 1.5 – 16
○ Width (mm): 914 – 2000
○ Coil weight: 15 – 25 tons (eye to sky or eye to side)
● Plates (cut from coils or mill plates):
○ Thickness (mm): 6 – 100
○ Width (mm): 1000 – 3000
○ Length (mm): 2000 – 12,000

Tolerances: As per ASTM A6/A6M, EN 10029, JIS G3193

● Construction & infrastructure (beams, columns, bridges)
● Shipbuilding & offshore structures
● Pressure vessels & boilers
● Pipelines & tanks
● General fabrication & machinery

● Coils:
○ Strapped with steel bands, edge protected, wrapped in waterproof paper & steel sheet.
○ Eye to sky or eye to side, depending on shipping method.
● Plates:
○ Bundled in lots of 2–5 tons, strapped with steel bands.
○ Wooden dunnage placed between layers for handling.
● Shipping:
○ Breakbulk (plates stacked with dunnage).
○ Containerized (20’ or 40’, max ~25 tons)
○ Coils shipped in bulk or containers with proper securing.
○ ISPM‑15 for wooden dunnage; photographic proof of loading available.
