The specifications of plastic steel door and window profiles are usually related to door and window structure, profile system and specific application requirements.
The sizes of frame profiles, sash profiles and mullions used for different types of doors and windows vary, so no single specification can meet all door and window processing needs.
When selecting profiles, door and window processing enterprises need to first confirm the main types of doors and windows to be produced, such as sliding windows, casement windows and other products.
After confirming the door and window system, match the corresponding main profiles and supporting profiles.
In addition to cross-section specifications, profile length, packaging method and batch stability will also affect the actual production of factories.
Large fluctuations in profile dimensions may affect cutting and welding processing.
Therefore, purchasers shall confirm complete specification documents with manufacturers instead of purchasing only by product names.
For long-term cooperative customers, fixed product codes and purchasing standards can also be established.
This can reduce specification confusion between different batches and orders, and help door and window processing factories build a more standardized production system.
