3.50 Safe to install
This comprehensive stair framing, decking, flooring, and concrete calculation tool is designed to serve carpenters, contractors, and builders requiring precise measurements and estimations. Its user-friendly interface minimizes complex data entry; users can begin inputting data in any field, with help and guidance accessible via double-tap on buttons.
The application facilitates the discovery of solutions under various restrictions related to tread dimensions, step rise, incline, and specific standards such as '2R+G' or '2R+TD'. Users may choose to apply all, some, or none of these restrictions based on their project requirements. Note: Pre-filled data should be verified against local building regulations, which vary significantly across regions; users should adapt settings accordingly.
Known for its accuracy and reliability, this tool is an essential resource for professionals engaged in stair framing, decking, and flooring construction. Developed by experienced carpenters and utilized worldwide by contractors and builders.
