The Stairs module in Graitec Advance Powerpack is highly versatile, using standard frames that can be easily edited and customized for specific requirements – either it’s a particular building plan or design or even narrow spaces. This tool contains all necessary elements to assemble straight or balanced stairs, with one, two or three flights.
Considering what parameters you choose, it will automatically suggest several treads, the height between two steps, goings, strides, meeting all user requests, from the most common to the most particular. It also calculates the pitch angle and, depending on the results, the stairs are framed into a certain category.
Design straight stair configurations that allow you to quickly create differing flight arrangements (either one, two, or three flights), depending on your needs.
L – shaped straight stair
Variate your straight stairs with L - shaped stairs, by adding a landing at the transition point at any bend suitable for your space and design.
U – shaped straight stair
Another variation of straight stairs offered by the Stairs module is the U - shaped stair, with a corner turn or middle landing that offers a resting point partway up the stairs.
L - shaped balanced stair
L – shaped balanced stairs are balanced stairs with a 90° turn, where the landing is replaced by balanced treads of different sizes.
U – shaped balanced stair
U – shaped balanced stair or balanced stairs with 180° turn are economical, in terms of space, given the fact that the treads also replace the landing.
Using the Stairs module with Advance Steel ensures high ergonomics and customization for most elements of the stairs: slope inclination, number of steps resulting, the length and distance between steps (rise).
For each type of stair (straight, half-turn, quarter turn, balanced) the module allows defining a different width for the last tread. Entering an appropriate value will result in a landing or a conversely top short stair.
The upper and lower treads of a staircase can be defined with the platform on which it will be created. This option allows users to choose how to define the stairs, so the treads will be either above or on the same level as the platform.
New types of stringers are featured, for stairs with open sides, between two walls or against a wall. The stringers can easily be adjusted from the dialog box, regardless of type (either open or closed).
In the case of open type stringer, its position is below the built-in steps, the flights being outside the stringer, fixed in the console.
The closed stringer is positioned at the end of the steps, bordering them.
