Maintenance Free

The exterior of all Openchannelflow single-piece shelters is a smooth, gloss finish.  Unlike “satin” finished shelters, the gloss finish of Openchannelflow shelters means that other than a periodic wash down, there is virtually no need for maintenance.    

The “satin” finish of other shelters can be used to hide a number of fabrication or finishing issues.  Satin finishes are also perfect surfaces for atmospheric dust, dirt, and debris to cling to and algae, moss, mold, and lichen to grow on - all of which are avoided by a gloss finish.

High Strength

Single-piece construction means that there are no joint to periodically seal or maintain.  Also, as Openchannelflow single-piece shelters are chemically bonded and then fiberglassed together, they are incredibly strong and capable of withstanding harsh conditions. 

Our X-Web technology bonds the inner and outer fiberglass skins together by creating a web (or I-beam) of fiberglass around each insulating core panel.  The result is wall / roof sections that are incredibly light yet which are, pound for pound, stronger than steel.

The standard single-piece shelter design is for:

  • Wind speeds up to 135 mph [217 kph]
  • Snow loads up to 45 psf [2.155 kPa]
  • Type III / U occupation group

with higher wind / snow load reinforced designs also available.
