This calculator is designed for calculating metal frame canopies. It is perfect for those planning to build a metal canopy and wanting to optimize the structure considering all necessary parameters. The calculator allows for online calculations without the need to consult specialists, saving both time and money.

Main features of the calculator:

  • Calculation of the canopy geometry, including span length, post spacing, and height of the structure.
  • Input of loads: snow load, wind load, and permanent load from roofing materials.
  • Selection of the section and grade of steel for posts, beams, and purlins, including rectangular tubes, channels, I-beams, and angles.
  • Optimization of sections considering strength, deflection, and stability of the structural elements.

Using the calculator is very straightforward:

  1. Step 1 "Geometry": Specify the main dimensions of the canopy – length, width, and height.
  2. Step 2 "Loads": Enter the values for snow load, wind load, and permanent loads.
  3. Step 3 "Section": Specify the type and dimensions of the metal elements used in the structure.
  4. Step 4 "Result": Obtain detailed calculation results with strength and stability indicators.

This metal frame calculator will help you accurately calculate the canopy structure and select optimal materials for its construction. You will be able to design a metal truss for the canopy, taking into account all project specifics.
