free calculators.
No sign-up, no export limit.
We built these for our own production floor to check a lug before it went to the shop, to prove a wall build-up against SBC 601, to price a steel package the same afternoon the BOQ landed. They are now public and free. Every calculator runs to a named code, shows the intermediate values rather than just a pass or fail, and exports a report you can attach to a submittal.
Calculate weights for rebar, beams (IPE/HEA/HEB), pipes, plates and angles” and generate a full PDF & Excel report with Saudi market prices. Arabic & English.
Calculate the U-Value of any wall or roof layer by layer, check compliance with the Saudi Building Code (SBC 601/602) for your city, and generate a print ready report supports block, sandwich panel, and cladding systems.
Calculate concrete quantities for all structural elements footings, columns, beams, slabs, rafts and piles with cement bags, sand, aggregate, rebar estimates and Saudi market costs. Print or export your quantities report instantly.
Enter your design reinforcement bar sizes, spacing and stirrups and get the steel weight per element with kg/m³ ratios, a live section drawing, and a diameter summary in tons and 12m bars ready for pricing.
Calculate properties of any concrete or steel section area, moment of inertia, section modulus and weight from official EN catalogues or custom dimensions, run color-coded stress analysis with 3D view and LRFD/ASD checks per Saudi code.
Design & verify welded lifting lugs (pad eyes) to AISC 360 or ASME BTH-1 — full code checks, sling angles, dynamic factor, and a consultant-ready calc note in seconds.
Score any project against all ten active LEED rating systems v5, v4.1 and v4. Checks the Minimum Program Requirements before it counts a single point, enforces prerequisites and the v5 Platinum gates, estimates GBCI and consultant cost in five currencies, and exports a branded PDF, a two-sheet Excel and a shareable link.
CFS Designer checks cold-formed steel purlins, girts and columns from simple site inputs span, spacing and surface loads. It builds the load combinations automatically (AISI S100 · EN 1993-1-3 · AS/NZS 4600), runs effective width member checks with web crippling and deflection, suggests the lightest passing section
