Civil Data
Section properties, reinforcement and material data used every day in structural design — searchable, mobile-friendly and wired into the calculators.
Steel H-Beam Sections
เหล็กรูปพรรณหน้าตัด H — Wide- and narrow-flange H-beams — area, weight, Ix, Iy, Sx, Zx and radii of gyration. Send any section straight into the weld calculator.
Steel Channels (C)
เหล็กรางน้ำ (เหล็กตัว C) — Hot-rolled channel sections with area, weight, centroid, Ix, Iy, Sx, Sy and radii of gyration.
Equal Angles (L)
เหล็กฉากขาเท่า — Equal-leg angles with centroid, Ix, minimum radius of gyration rv for bracing and truss members.
Hollow Sections (Box)
เหล็กกล่องสี่เหลี่ยมจัตุรัสและผืนผ้า — Square and rectangular tubes — area, weight, Ix, Iy, Sx, Sy, Zx and radii of gyration.
Reinforcing Bars
เหล็กเสริมคอนกรีต — Round (RB) and deformed (DB) bar sizes with nominal area, weight per metre and perimeter, plus an area-per-count table.
Fillet Weld Data
ข้อมูลรอยเชื่อมพอก — Electrode strengths and allowable throat shear, code minimum and maximum fillet sizes, and weld capacity per centimetre.
Steel & Concrete Grades
เกรดเหล็กและคอนกรีต — Yield and tensile strength of rebar and structural steel grades, and concrete strength classes with modulus of elasticity.
