The Haoran HR-A-018 in-ground square tube Brunei-Muara Districtbasketball hoop is manufactured by Cangzhou Haoran Sports Equipment Co., Ltd., China. Below are its detailed specifications:

I. Main Structural Parameters

* Main Pole Material and Specifications:

* 18cm×18cm thickened square tube, 5mm wall thickness, ensuring structural stability.

The main pole is fully welded using a fully automated welding robot, resulting in high weld strength and eliminating issues such as incomplete welds or cracks.

Extendant Arm Design:

* Extendant arm length is 2.25 meters, employing a double-layer reinforcement structure:

* Main Arm: 8cm×12cm square tube

* Sub-arm: 5cm×8cm square tube

* Connected to the uprights via three-point tie rods, forming a five-point support system capable of withstanding significant impact.

In-ground Reinforcement System:

* Equipped with 80cm×80cm×100cm reinforced concrete embedded parts, with an internal Φ16mm threaded steel welded frame.

After the embedded parts are buried underground, C30 concrete needs to be poured and compacted to fix them, forming an integrated load-bearing structure with high resistance to overturning moment.

II. Backboard and Rim Parameters

Backboard Specifications

Dimensions: 1800mm × 1050mm, conforming to international standards.

Material: High-strength tempered glass, 10mm to 12mm thick, high transparency, strong weather resistance, anti-aging, and corrosion resistance.

Edge: Aluminum alloy edging around the perimeter, with a new type of shock-absorbing rubber pad at the bottom for enhanced stability.

Rim Configuration

Using a new improved elastic solid steel rim, φ20mm in diameter, standard professional configuration.

Equipped with a spring mechanism to withstand instantaneous impact, ensuring rim stability during shooting and the safety of dunkers.

III. Surface Treatment and Protection

Material and Process

The main shaft and extension arm are made of Q235 national standard steel. The surface is mechanically sandblasted to remove rust, smoothed, and polished, then coated with pure polyester powder.

The coating thickness is 70-80μm, with a pencil hardness of 3H+. It has passed a 36-hour salt spray test and is resistant to acids, alkalis, damp heat, and aging.

Safety Protection Design: The front post, backboard, and extension arm are equipped with special protective sleeves made of rigid sponge to effectively protect athletes from impacts.

The base has a shock-absorbing pad to reduce shaking and noise.

IV. Other Parameters
