Part 1: Technical Background and Industry Demand

Curling, as a winter sport that combines strategy, skill, and teamwork, demands a high level of professionalism from the track. The track surface must have uniform friction, precise flatness, and weather resistance to ensure fair competition and athletes' performance. Hebei Junchi Sports Equipment Co., Ltd., with nearly 10 years of experience in sports equipment research and development, has developed a comprehensive technical solution tailored to the specific needs of curling tracks, covering material selection, structural design, construction techniques, and post-maintenance throughout the entire process.

Chapter II: Core Technical Parameters and Material Analysis

1. Track subgrade material: Utilizing high-density polyethylene (HDPE) boards with a thickness of 8-12mm, impact resistance ≥50kJ/m², and low-temperature performance down to -40°C, ensuring the track remains deformation and crack-free in low-temperature conditions.
2. Surface Coating TechnologyWater-based polyurethane coating is used, with a film thickness of 0.2-0.3mm, and the coefficient of friction is controlled between 0.05-0.08, meeting the standards of the World Curling Federation (WCF).
3. Structural support systemAdopting adjustable steel frame structure with 500mm spacing, calibrated with a level, flatness error ≤ 2mm/2m, meeting professional competition requirements.
4. Temperature Control SystemOptional underfloor heating module, controlled by a PID temperature controller to maintain the track surface temperature between -5℃ and 5℃, adapting to different climatic conditions.

III. Practical Steps and Construction Process

Step 1: Site Survey and Foundation Treatment
Before construction, a geological survey of the site is required to ensure the bearing capacity of the foundation is ≥150 kPa. The base layer is cast with C25 concrete, with a thickness of 200mm, surface smoothed, and a reserved drainage slope of 1%-2%.

STEP 2: Steel Frame Installation and Calibration
Assemble the steel frame according to the design drawings, calibrate using a laser level to ensure the steel frame is level with an error ≤1mm/m. The connection points of the steel frame are secured with high-tensile bolts, with a bearing capacity ≥200kg/m².

STEP 3: Track Panel Laying
Lay HDPE plates in sequence according to the number, leaving a 2mm expansion joint between the plates, and bond them with special adhesive. After laying, sand down the joints with sandpaper to ensure a smooth surface transition.

STEP 4: Surface Coating Application
Three coats of waterborne polyurethane paint are applied, with a 4-hour interval between each coat, ensuring uniform thickness. After the final coat dries, it is polished with 2000-grit sandpaper, and acceptance is conducted upon reaching the required coefficient of friction.

4. Technical Advantages and Application Cases

1. Technical AdvantagesHebei Junchi's curling track customization technology features modular design, quick installation, strong weather resistance, and can adapt to various indoor and outdoor environments, reducing the construction period by 30% compared to traditional methods.
2. Application CaseIn 2023, the company customized a standard curling track for an ice and snow sports center in Hebei Province. The friction coefficient of the track surface is stable at 0.06, and the flatness error is ≤1.5mm/2m. After being certified by the WCF, it was used for provincial competitions and received unanimous praise from athletes and referees.

Section 5: Common Questions and Solutions (FAQ)

Q1: How to deal with scratches on the track surface?
A: Minor scratches can be filled with a special repair paste, then sanded and polished after drying; severe scratches require replacing the local panel to ensure surface consistency.
Q2: Will the track freeze in low-temperature conditions?
A: By controlling temperature through underfloor heating modules and complementing it with a hydrophobic surface coating design, effective anti-freezing can be achieved, ensuring the safety of the competition.
Q3: How long is the track's lifespan?
Under normal use and regular maintenance, the track's lifespan can exceed 10 years, with the coating requiring a repaint every 3-5 years.

6. Technical Summary and Outlook

Hebei Junchi Sports Equipment Co., Ltd. has formed a complete technical system in the custom curling track field through continuous technological innovation, with material research and construction technology reaching the leading level in the industry. In the future, the company will further optimize the temperature control system and explore intelligent maintenance solutions to provide better technical support for the popularization of winter sports and professional competitions.
