STEEL STRUCTURE PROCESSING
1. Cutting
Machines Used: CNC Plasma Cutters, CNC Flame Cutting Machines, Hydraulic Shears
Description: Precision cutting of steel plates and structural components. Plasma and flame cutting are suitable for thick steel plates, while hydraulic shearing ensures smooth edges and accurate dimensions for thinner materials.
2. Forming
Machines Used: CNC Press Brakes, Cold Bending Machines, Rolling Machines
Description: Used for shaping steel components such as purlins, gutters, flashing trims, curved beams, and cylindrical structural parts with high dimensional accuracy.
3. Welding
Machines Used: Submerged Arc Welding (SAW), Manual Arc Welding, CO₂ Gas Shielded Welding
Description: SAW is commonly used for H-beams and H-columns, while manual welding is applied to connection plates and reinforcement parts. CO₂ welding ensures clean and strong welds for thin-walled steel sections.
4. Hole Making
Machines Used: CNC Drilling Machines, Hydraulic Punching Machines
Description: CNC drilling provides highly accurate bolt hole positioning for structural assembly. Hydraulic punching is suitable for standard hole patterns and efficient batch production.
5. Surface Treatment
Machines Used: Shot Blasting Machines, Sand Blasting Equipment, Grinding Tools, Hot-Dip Galvanizing Line
Description: Surface preparation removes rust, scale, and contaminants. Grinding improves weld appearance, while hot-dip galvanizing provides long-term corrosion resistance for structural steel components.
6. Assembly
Machines Used: Assembly Platforms, Laser Measuring Tools, Alignment Jigs
Description: Pre-assembly of steel columns, beams, trusses, and bracing systems is performed to verify dimensions, fit-up accuracy, and structural integrity before shipment.
STEEL STRUCTURE TESTING
1. Salt Spray Test
Standard(s): ASTM B117, ISO 11997-1
Purpose: Evaluates corrosion resistance of galvanized and coated steel products, particularly for coastal, humid, and marine environments common in Central America and tropical regions.
2. Adhesion Test
Standard(s): ISO 2409 / ASTM D3359 (Crosshatch), ISO 4624 / ASTM D4541 (Pull-Off)
Purpose: Measures the bonding strength between the coating and steel substrate to prevent peeling, flaking, or coating failure during service.
3. Humidity & Heat Resistance Test
Standard(s): ASTM D2247 (40°C / 95% Relative Humidity)
Purpose: Assesses coating performance under high-temperature and high-humidity conditions, ensuring resistance to blistering, cracking, and moisture penetration.
4. UV Aging Test
Standard(s): ASTM G154
Purpose: Simulates long-term sunlight exposure to evaluate resistance to fading, chalking, discoloration, and coating degradation caused by ultraviolet radiation.
5. Film Thickness Test
Standard(s): ASTM D7091 (Dry Film Thickness), ASTM D1212 (Wet Film Thickness)
Purpose: Verifies that coating thickness complies with project specifications and provides adequate corrosion protection.
6. Impact Strength Test
Standard(s): ASTM D2794 (Drop Hammer Impact Test)
Purpose: Evaluates the coating’s resistance to mechanical damage during handling, transportation, installation, and storage.
These testing procedures ensure that steel structures, steel pipes, H-beams, sheet piles, and other fabricated steel products maintain excellent durability and long-term performance in demanding project conditions.
