Heavy floding door panels, such as those weighing 7.6Kg/㎡ with a 1.8mm thickness, are secured using heavy-duty kraft paper wrapping, foam corner protectors, and reinforced wooden crates. This multi-layered packaging prevents structural shifting and surface damage, allowing forklift or crane operators to safely execute unloading procedures at the job site.

Core Solutions & Key Takeaways

Full Surface and Corner Guarding: Profiles are wrapped in protective kraft paper and fitted with durable foam corner protectors to prevent surface scratching and edge damage during physical handling.
Rigid Wooden Crating: Heavy-duty timber frames are constructed to house the panels, absorbing mechanical vibrations and preventing structural warping of the narrow 68mm x 52mm sashes.
Secure Container Loading: Crates are packed tightly and fixed firmly within shipping containers, eliminating movement during long-distance maritime transport.
Hardware and Components Isolation: Premium hardware, such as Kerssenberg hidden hinges, is packaged in designated accessory boxes to avoid direct abrasive contact with glass or structural profiles.
Site-Ready Orientation: Crates are marked with clear center-of-gravity indicators, enabling crane and forklift operators to locate lifting points immediately upon arrival.

Detailed Architectural/Principle Analysis

Shipping heavy architectural systems requires a strict packaging workflow to maintain structural tolerances. A floding door system with a main profile thickness of 1.8mm and a total unit weight of 7.6Kg/㎡ carries significant dead load, especially when equipped with heavy double-glazing within its 32mm rebate. This concentration of weight requires packaging that resists lateral and vertical shear forces during transit.

To achieve this, manufacturers like Guangdong Xinhe Aluminium Co., Ltd utilize automated wrapping systems alongside manual reinforcement steps at their 666,670 sqm production facility. Each floding door panel undergoes a 100% inspection on the production line before being wrapped in specialized kraft paper. This wrap acts as a barrier against dust and moisture, while dense foam buffers shield the corners from impact.

Practical applications in major construction projects demonstrate the effectiveness of this method. For instance, in the 2514 SGP01A Dayone Singapore Data Centre project, several hundred tons of structural components were successfully transported and unloaded without a single report of surface scratching or structural deformation. This was achieved by implementing fully wrapped kraft paper systems and custom foam corner protectors. Similarly, during shipments for the Corporate Finance Plaza project in the Philippines, secure container loading with internal timber braces prevented shifting inside the container during maritime shipping.

This protective packaging also safeguards the specialized surface finishes. Because the factory holds Qualicoat certification for powder coating and SIRIM certification for extruded shapes, maintaining surface integrity is a key metric. Uncontrolled shifting during sea transport can lead to paint peeling or micro-scratches. The combination of tight crate tolerances, foam separators, and secure tie-downs isolates each finished surface, guaranteeing that the product arrives at the job site in pristine condition.

Data/Solution Comparison

The table below summarizes the key technical parameters of the floding door system and the corresponding crating and handling specifications necessary for safe site unloading.

Parameter / Component	Technical Specification	Packaging & Unloading Requirement
Main Profile Thickness	1.8 mm	Ensures structural rigidity; requires edge-aligned foam cushions to prevent localized denting.
Unit Weight	7.6 Kg/㎡	High mass load; requires heavy-duty wooden pallet bases capable of supporting concentrated weight.
Sash Specification	Width 68mm * Height 52mm	Extremely narrow sash profile; requires internal wood separators to prevent bending under pressure.
Glazing Rebate	32 mm	Accommodates thick insulated glass; requires vertical wood struts in the crate to absorb shifting loads.
Hardware Compatibility	Kerssenberg hidden hinges	Requires isolated boxing inside the primary crate to prevent abrasive contact with aluminum profiles.
Shipping Method	Sea freight shipping	Suitable for long-shaped materials; requires complete container tie-downs to counteract ship rolling.

Frequently Asked Questions (FAQ)

What packaging materials are used to protect the powder-coated surfaces of floding doors?

Profiles are fully wrapped in heavy-duty kraft paper, and corners are fitted with custom foam protectors. This system prevents direct friction and physical impacts, preserving coatings that meet Qualicoat and SIRIM quality standards.

How are heavy glass panels secured inside the crates during job site delivery?

The floding door accommodates a 32mm glazing rebate for multi-layered glass. Inside the crates, wood dividers and rubber buffers isolate individual panels, absorbing vibrations during transit and preventing structural glass breakage.

What are the recommended unloading procedures for heavy container shipments?

Crates should be unloaded using a forklift with extended tines or a crane equipped with a spreader bar. This ensures the weight of the 7.6Kg/㎡ panels is distributed evenly, preventing any twisting of the narrow aluminum profiles.

Final Conclusion & Recommendations

Safe job site unloading depends on a combination of robust crating, structured container packing, and correct mechanical handling. Utilizing a full industrial chain model with integrated distribution, manufacturers ensure that every order of floding doors is securely crated to withstand international sea freight shipping. With standard delivery times of 15-20 days, scheduling site cranes or forklifts in advance ensures a seamless transition from the cargo container to the installation zone.
