Technical notes and recommendations of the system STEELTELHAARCO

1. The edges of the roof must be parallel to each other as all of the panels, which make up the system, are the same length.

2. The supports at the ends, on articulated metal ridges, must be linear and parallel, and on straight supports for each side.

3. The system consists of identical units, deep rippled metal slats that overlap along their longitudinal axis for interlocking. The units are mechanically fixed on site by means of screws at regular intervals.

4. The system, by virtue of it being a membrane, can be distorted, which enables it to absorb the stresses arising from wind or other loads by evenly distributing and transmitting the forces to its supports.

5. The system does not allow interruptions in the continuity of its surface. It is a complete uninterrupted panel-to-panel system of identical length.

6. Skylights can be incorporated for natural light by locating translucent elements that are specifically designed for the system. It is not advisable to make any alteration to the structural continuity formed by the roof panels.

7. The panels do not support rigid profiles or joints that restrict or even affect the “curved shape”, which would increase the forces on the mechanical joints and alter the essence of the system.

9. The system has lateral supports that are located linearly on articulated metal ridges. These are linked together by indispensable steel cables for transmitting tensile forces, wind and wind bracing.

10. Thermal expansion is absorbed by the shape of the membrane itself by slightly increasing or decreasing its rise. There is therefore no need for longitudinal or transverse expansion joints. This feature makes it self-compensating.

11. The weight of excess snow is transmitted to the system, which increases the tension of the bracing cables.

12. The system’s cables and wind braces protect the original shape or curvature against any external forces. This makes the distortion of the membrane slight and controlled.
