Product Description

Hot Rolled Ms Angel Steel S235jr S275jr S355jr Carbon Steel 45 Degree Steel Angle Bar Size

Product Description

Angle Bar (Angle Steel)
Angle bar (also known as angle steel or angle iron) is a long steel product with an L-shaped cross-section, consisting of two mutually perpendicular legs with a typical internal angle of 90°.
Core Features:
Simple cross-section section steel, classified as carbon structural steel for construction
Excellent compressive and bending resistance with a high strength-to-weight ratio
Easy to process, weld, and install, with minimal space occupation
Classification & Specifications
1. Classification by Shape
Equal Angle Bar: Legs of equal width (e.g., ∠50×50×5mm)
Unequal Angle Bar: Legs of unequal width (e.g., ∠100×80×8mm)
2. Specification Expression
Equal Angle Bar: Leg width × Leg width × Leg thickness (mm) - e.g., ∠50×50×5 or simplified as ∠50×5
Unequal Angle Bar: Long leg width × Short leg width × Leg thickness (mm) - e.g., ∠100×80×8
Model Designation: Size number is based on leg width in centimeters (e.g., Size 3# refers to an equal angle bar with 30mm leg width)
3. Size Range
Equal Angle Bar: Domestic specifications: 2#~20# (20mm×20mm~200mm×200mm)
Unequal Angle Bar: 25mm×16mm~200mm×125mm (thickness: 4~18mm)
Classification by Size:
Large: Leg width > 125mm
Medium: 50mm < Leg width ≤ 125mm
Small: Leg width ≤ 50mm
4. Theoretical Weight Calculation
Equal Angle Bar: W (kg/m) = 0.00785 × Leg thickness × (Leg width + Leg width - Leg thickness)
Unequal Angle Bar: W (kg/m) = 0.00785 × Leg thickness × (Long leg width + Short leg width - Leg thickness)
Material & Properties

Material Type	Typical Grade	Yield Strength	Features & Applications
Carbon Structural Steel	Q235 Series (A/B/C/D)	235MPa	Good ductility and weldability; suitable for general construction and non-load-bearing components
High-Strength Low-Alloy Steel	Q355 Series (A/B/C/D/E)	355MPa	High strength; allows thinner thickness for material savings in bridges and pressure vessels
Stainless Steel	304/316	205-250MPa	Excellent corrosion resistance; used in food processing, medical equipment, and marine environments
Galvanized Angle Bar	Q235B + Hot-Dip Galvanized	235MPa	Atmospheric corrosion resistance; ideal for outdoor and humid environments
Aluminum Alloy	6061/6063	110-275MPa	Lightweight and corrosion-resistant; applied in aerospace, marine, and furniture industries

Application Fields
1. Building & Construction
Building frames, roof trusses, and stair handrail supports
Curtain wall keel systems (Q235B hot-dip galvanized angle bars)
Door/window frames and balcony railings
2. Infrastructure

Power transmission towers and communication tower skeletons
Highway guardrail posts
3. Industrial & Machinery
Equipment frames, conveyor supports, and machine bases
Fabrication of storage racks, shelves, and workshop platforms
Pressure vessel brackets and boiler supports (Q355 series)
4. Marine & Offshore
Ship hull frames and deck supports (stainless steel/galvanized angle bars)
Offshore platform auxiliary structures
Port and dock fendering systems
5. Other Applications
Automotive manufacturing (chassis components)
Furniture production (table legs, shelf brackets)
Agricultural machinery and irrigation systems
Key Notes for International Trade
Material Certification: Provide mill test certificates (MTC) per EN 10204 3.1B or ASTM standards for export
Surface Treatment Options: Hot-dip galvanizing (HDG), electro-galvanizing, or black oxide finish (per customer requirements)
Packaging: Bundled with steel straps (2-3 tons per bundle) + waterproof paper + fumigated wooden pallets (compliant with ISPM 15)
Customization: Accept OEM/ODM for special sizes (e.g., unequal angle bars with non-standard leg ratios) or alloy materials
