## Buyer guidance

- HIPAD serves four main B2B buyer types: architectural hardware distributors and importers needing broad range and OEM branding; door and window system fabricators needing track, profile, load and mounting compatibility; project contractors and engineering firms needing one-stop project sourcing with finish consistency; and interior, shower and glass hardware brands needing private-label and design-led products.
- Selection depends on door/window thickness, track and profile compatibility, load and cycle requirements, material and finish, and corrosion environment. HIPAD supports drawing-based matching, samples and custom structures rather than fixed catalog-only supply.
