The Challenge: Balancing Shipping Costs and Quality Testing
A valued client recently decided to order our flagship automatic door operator but expressed concerns over the high international
shipping costs associated with full-sized components. To help them minimize freight expenses on their initial trial,
we mutually agreed to forego the full-sized automatic door track and cover in this shipment.
However, to properly evaluate the build, the client initially requested tiny 2–3 cm snippets for material inspection.
Our Professional Solution: Going Beyond Micro-Samples
Drawing on our extensive industry experience, our engineering team knew immediately that 2–3 cm sections were simply
too small to properly demonstrate the true durability, finish, and structural integrity of the material.
Instead of taking a shortcut, we proactively custom-cut 10 cm precision samples of both the automatic door track and cover.
This thoughtful adjustment provides our client with a comprehensive, tactile evaluation of our product quality without forcing
them to bear the heavy burden of full-length shipping fees.
