What to Look for in a Manufacturer
Factory visit — can they show you their production line? Client references — ask for past clients with similar projects and call them. Certifications — for fire shutters, the fire rating test report is non-negotiable. Warranty terms — what's covered and what's the response time for service calls? A standard door should take 7 to 15 days from order confirmation. Price is not the only factor: the cheapest supplier often becomes the most expensive after repairs and downtime.
