1. Characteristics of mining steel

• High load-bearing capacity : Designed to withstand heavy loads, vibrations, and continuous impact from ocean waves.

• High corrosion resistance : Can be galvanized or alloyed, or made of a type of steel with marine corrosion resistance (such as alloy steel, or using special epoxy coatings).

• Easy to weld and machine : Suitable for industrial welding and CNC cutting methods.

• Meets stringent international standards : Mining steel typically requires certification from international classification societies such as ABS, BV, DNV, LR, KR, and NK .

2. Common types of mining steel

Type of steel	Common form	Technical standards	Main applications
Flat steel bulb	The letter "B"	ASTM, EN, JIS, ABS	Bottom of the ship, frame, bulkheads
Load-bearing steel plates	Flat panel	AH32, AH36, DH36, EH36 (ABS, LR…)	Deck, main frame structure
H-shaped steel	H-beam	JIS G3101 SS400, ASTM A36	Frame columns, jetties, drilling rigs
Thick steel pipe	Seamless steel pipe	API 5L, ASTM A106, A53	Oil pipeline, platform structure

3. Practical Applications

• Shipbuilding industry : Ship frames, hulls, bottoms, bulkheads, decks.

• Oil and gas drilling rig : Support pillars, rig frame, high-pressure oil and gas pipelines.

• Coastal structures : Piers, offshore oil rigs, offshore guardrails.

• Special steel structures : Suitable for environments with salt spray, humidity, and strong vibrations .

4. Specifications & Technical Data

5. Advantages of mining steel

• High mechanical strength, suitable for large structures.

• Excellent corrosion resistance when operating in a seawater environment.

• Long lifespan, low maintenance costs.

• Easy to combine with other materials in construction.
  
  
  

6. Notes when choosing mining steel

• A quality certificate (CO-CQ) and a maritime registration certificate are required .

• Ensure compliance with international technical standards relevant to the intended use.

• Check the origin and source of the goods carefully to avoid buying counterfeit or fake products.
