Sectional door strap

How many sectional doors have been sent to the skip prematurely because the straps used in their manufacture have prematurely deteriorated?
How many disgusted customers have changed suppliers because the tiny "saving" made on the import of these straps had ruined the entire door, or shifted its delivery date despite common sense?
One of our seven webbing factories specializes in this type of 70 mm non-stretch webbing(or other, depending on the technical constraints of each manufacturer). They deliver dozens of tons every year, and you can consult us with complete confidence.
