Plate girder replacement involves removing and substituting old or damaged girders with new ones to restore structural integrity. Fabrication includes cutting, welding, and assembling steel plates to create custom girders tailored to project specifications. The structure ensures load-bearing capacity and stability, often used in bridges and large buildings.

Size: Typically spans 10m to 50m in length, 1m to 3m in depth, and 0.5m to 2m in width.

Grade: Commonly uses steel grades such as ASTM A36, ASTM A572, or EN 10025 S355.

Viscosity: Not applicable to structural steel; relevant only for coatings or paints (e.g., epoxy viscosity: 500–2000 cP).

Buoyancy: Negligible for steel plate girders; density of steel (~7850 kg/m³) prevents buoyancy in water.

Material: Primarily fabricated from carbon steel or high-strength low-alloy (HSLA) steel.

Weight: Varies by size and material, typically 200 kg/m to 1500 kg/m.

Load Capacity: Designed for 20 kN/m² to 50 kN/m², depending on span and reinforcement.

Corrosion Protection: Hot-dip galvanizing or painted coatings (e.g., 60–150 microns dry film thickness).

Welding Standards: Complies with AWS D1.1 or EN 1090 for fabrication.

Surface Finish: Mill scale, blasted (SA 2.5), or painted, as per project requirements.
