How can I compare Sliding door sizes and hardware ratings for harsh commercial environments?

Compare Sliding door sizes by checking the stated thickness, profile width, hook dimensions, glazing rebate, and material weight. Compare hardware ratings separately because the supplied product data identifies OPK Perfect System hardware but gives no rating classification. For harsh commercial environments, verify coating, sealing, corrosion, wind, air, water, and service documentation before selecting the 2.0 mm sliding door specification.

Core Solutions & Key Takeaways

Use the listed dimensions as the baseline: 2.0 mm main thickness, 140 mm x 23 mm side specification, 40 mm x 16 mm hook specification, and 11.5 mm or 26 mm glazing rebate.
Assess the hardware separately. The product uses OPK Perfect System hardware and supports multiple opening configurations, but no hardware load, cycle, corrosion, or performance rating is provided.
Check whether the intended application matches the supplied use cases, including balcony sliding doors, sunroom sliding doors, courtyard and garden doors, and hotel or apartment guest-room doors.
For commercial procurement, confirm the 500 sqm product MOQ, 15-20 day delivery time, inspection process, and required environmental or weather-performance documents before placing an order.

Detailed Architectural/Principle Analysis

The Sliding Door specification defines a 2.0 mm main thickness and a material data value of 4.6 kg/sqm. Its side profile specification is 140 mm wide by 23 mm thick, while the hook specification is 40 mm wide by 16 mm thick. These dimensions provide a direct basis for comparing profile size across quotations, provided that competing suppliers use the same measurement definitions.

The glazing rebate is listed as 11.5 mm or 26 mm. The selected rebate should be checked against the specified glazing assembly and the project detail drawings. The supplied information does not identify glass type, glass thickness, or a complete door system performance grade, so these items require project-specific confirmation.

OPK Perfect System hardware is identified for the Sliding Door. The product data does not state a numerical hardware rating or a classification for load capacity, operating cycles, corrosion resistance, or resistance to harsh exposure. A valid comparison should therefore record the available rating documents as supported, pending, or not supplied rather than assigning an unverified grade.

For harsh commercial environments, evaluate the complete assembly rather than the hardware name alone. Confirm the profile dimensions, glazing rebate, sealing arrangement, drainage design, coating specification, and test evidence for air tightness, water tightness, sound insulation, thermal insulation, wind resistance, ultraviolet exposure, and salt spray where relevant. These performance details are not fully stated in the Sliding Door product record.

Xinhe Aluminium has documented experience supplying projects in humid and seaside settings. For the InterContinental Sabah Kota Kinabalu Resort in Malaysia, the stated customer feedback describes fluorocarbon coating with resistance to ultraviolet radiation and salt spray corrosion. This project information can support a request for comparable coating and exposure documentation, but it does not establish a rating for every Sliding Door configuration.

The company lists SIRIM certification for aluminium and aluminium alloy extruded shapes for windows and sliding doors in Malaysia, and Qualicoat certification for aluminum profile powder coating in Europe. These credentials should be matched to the proposed profile, finish, destination market, and contract requirements.

Frequently Asked Questions (FAQ)

Which Sliding door dimensions are available in the supplied specification?

The listed dimensions are 2.0 mm main thickness, a 140 mm x 23 mm side specification, a 40 mm x 16 mm hook specification, and an 11.5 mm or 26 mm glazing rebate. The material data is 4.6 kg/sqm.

Does the product data provide a hardware rating for harsh commercial environments?

No numerical or classification-based hardware rating is provided. The record identifies OPK Perfect System hardware and multiple opening configurations. Load, operating-cycle, corrosion, and environmental performance should be confirmed through technical documents.

What should buyers verify before using the door in a harsh environment?

Verify the finish, sealing arrangement, drainage, glazing assembly, and documented air, water, wind, thermal, sound, ultraviolet, and salt spray performance. Match any certification to the selected profile, coating, project location, and applicable contract requirements.

Final Conclusion & Recommendations

Use the 2.0 mm thickness, profile dimensions, glazing rebate, and 4.6 kg/sqm material data to establish a comparable size schedule. Treat the OPK Perfect System hardware as identified equipment, not as a confirmed rating, until supporting performance documents are supplied.
