Frequently Asked Questions
What glass thicknesses work with standard flush mount channels?
Standard channels accommodate 6mm to 19mm tempered glass. Most commercial applications use 10-12mm glass for balancing cost, safety, and structural requirements. Thicker glass (15-19mm) is typically specified for high-traffic areas or enhanced security requirements. Custom channels can accommodate non-standard thicknesses with 3-4 week lead times.
How do I specify the right stainless steel grade?
304 stainless works for interior and most exterior applications in non-coastal areas. 316 stainless is specified for pool areas, coastal environments (within 1 mile of saltwater), and areas with chemical exposure. 316L stainless fabrication provides maximum corrosion resistance for direct marine exposure or industrial chemical environments. Cost difference between grades is typically 20-30%, but service life differences can be significant.
What’s involved in custom flush glass manufacturing?
Custom manufacturing starts with your architectural drawings and site requirements. Common modifications include non-standard lengths, curved sections, integrated lighting channels, and special mounting configurations. Lead time is typically 4-6 weeks for standard modifications, 6-8 weeks for complex custom work. Minimum quantities may apply depending on the degree of customization.
How do flush mount systems handle thermal expansion?
Thermal expansion is managed through expansion joints at 20-foot intervals for exterior installations. The flush design allows movement within the channel while maintaining glass retention. Interior applications typically don’t require expansion joints unless spanning large temperature differentials. Engineering calculations are provided for projects with specific thermal requirements.
What maintenance do flush mount glass channels require?
Routine maintenance involves quarterly cleaning of glass and channels, annual inspection of fasteners and gaskets, and checking for proper drainage. The flush design eliminates debris collection points that plague traditional raised hardware systems. Gasket replacement is typically required every 8-10 years depending on UV exposure and environmental conditions.
Are there load limitations for flush mount systems?
Standard flush mount channels exceed IBC horizontal load requirements (50 lbs/ft) with capacity up to 200 lbs/ft. Vertical loads up to 200 lbs concentrated load are handled without issue. For applications exceeding these parameters (such as crowd loading scenarios), custom engineering and reinforcement options are available through our ODM services.
