What does WF 40 × 12 × 392# × 12M A572 mean?
In the Philippines, where infrastructure and high-rise development continue to grow rapidly, engineers and contractors often specify large structural sections. One common designation is:
WF 40 × 12 × 392# × 12M A572
Each part of this specification provides crucial information about the beam’s dimensions, weight, and material. Understanding it helps project teams select the right section for bridges, commercial buildings, power plants, and industrial facilities across the country.
WF
This stands for Wide Flange H-Beam, also called a “W-section.” Wide flanges give these beams excellent load-carrying capacity and stability for columns, girders, and long spans — critical in Philippine construction, from expressways to large malls.
40
The nominal depth of the beam.
· “40” = 40 inches deep (≈ 1,056 mm).
· Such a tall section is ideal for the heavy demands of Philippine infrastructure projects and long-span structures.
12
The flange width.
· “12” = 12 inches wide (≈ 314 mm).
· Wide flanges add bending resistance, especially valuable in the Philippines where seismic and wind loads must be factored into designs.
392#
The weight per foot of the beam.
· “392#” = 392 pounds per foot (≈ 584 kg per meter).
· This is a jumbo H-beam, extremely heavy-duty, perfect for the large-scale bridges, ports, and industrial plants being built throughout the Philippines.
12M
The length of the beam.
· “12M” = 12 meters long.
· Standard mill lengths simplify transport and handling — important in Philippine logistics where beams must be delivered from warehouses to construction sites efficiently.
A572
The material grade.
· ASTM A572 is a high-strength, low-alloy structural steel.
· Commonly specified in Grade 50 (minimum yield strength 345 MPa), it provides greater durability than ASTM A36.
· This makes it a preferred choice for Philippine projects that demand both strength and resilience.
Why Does This Matter in the Philippines?
Being able to read H-beam sizes quickly helps Filipino engineers, contractors, and procurement teams:
· Select the right sections for safety and compliance with local building codes.
· Communicate clearly with steel suppliers like Acersteel.
· Support the nation’s “Build Better More” program, where massive infrastructure and industrial works require jumbo H-beams.
