A clearspan structure including component systems, and methods of forming a clearspan structure including component systems, for mitigating hazards to personnel or equipment from explosions, fires, toxic material release, and other hazards in hazardous locations. The exemplary clearspan structure is also capable of withstanding environmental conditions such as snow loads and wind. The exemplary clearspan structure is, for example, a tent or fabric structure which includes a plurality of frame members forming a support system for the clearspan structure, and fabric roof portions and walls for enclosing the clearspan structure.

An awning keder includes an awning bead extending along a length of the keder that is sized for insertion into a keder rail, and a connecting panel coupled with the awning bead and extending along the length of the keder. The awning bead and the connecting panel are integrated into a one-piece keder. The one-piece component does not require additional assembly or alteration before welding onto a vinyl canopy, thereby cutting down on production time. The keder is also more durable and less susceptible to expansion or shrinkage resulting from environmental changes.

A fabric panel attaching system and methods of assembly and use are presented for attaching fabric panels to structural elements, such as building frames. In various embodiments, the fabric panel attachment system includes a keder rail fastened to support bar, which is attached to a structural profile, such as a building frame member. In some embodiments, the keder rail is fastened to a support bar with bolt and nut. One or more fabric panels are installed within channels of the keder rail. An alignment element may be used with a fastener to assist in aligning abutting sections of keder rail. In various embodiments, the fabric panel attachment system is secured to flat or curvilinear faces of the structural elements. In some embodiments, the fabric panel attachment system may secure directly to the structural element and not a support bar.

The invention relates to a greenhouse, specifically a closed greenhouse environment suitable for use in dry environments which regulates the conditions of the growing environment whilst minimising heat and water loss. The greenhouse is especially suitable for use with macrophyte growing systems.
