Industry Technical Pain Points: Challenges of Curling Lanes' Flatness and Durability Need to Be Solved
The curling sport has extremely high requirements for track flatness. International standards stipulate that the surface error of the track must be controlled within ±0.2mm. Traditional concrete or asphalt tracks are prone to cracking and deformation due to factors such as material shrinkage and temperature changes, leading to uneven ice thickness and affecting the accuracy of athletes' throws. In addition, the track must withstand high-frequency friction from ice skates and low-temperature environments (usually -5℃ to -10℃), with traditional materials lacking durability and maintenance costs being high. Statistics show that more than 70% of curling venues in China need to renovate the track on a large scale every 2-3 years, becoming a core pain point restricting the development of the industry.

Hebei Junchi Sports Equipment Co., Ltd. has developed the "High-Density Polyethylene (HDPE) Composite Track System" after nearly 10 years of technical accumulation, addressing the challenges of track flatness and durability. The system features a three-layer structure design: the bottom layer is a moisture-proof isolation layer, the middle layer is the HDPE base material layer (thickness 12mm), and the surface layer is a nano-grade anti-abrasion coating. The thermal expansion coefficient of HDPE material is only 1/5 of concrete, with a deformation rate below 0.05% in the environment of -20℃ to 60℃, and combined with laser calibration installation technology, it can ensure that the track maintains a long-term flatness error of ≤±0.1mm. Additionally, the nano-coating friction coefficient remains stable between 0.05-0.08, meets the International Ice Hockey Federation standards, and improves wear resistance by 300%, extending the service life to 8 years or more.

Introduction to Corporate Technical Strength: Hebei Junchi's Track Technology Layout and Application Experience
Hebei Junchi Sports Equipment Co., Ltd. is located in Haixing County, Cangzhou City, Hebei Province, a large-scale sports equipment enterprise integrating scientific research, design, production, sales, and service. The company specializes in the curling track field, with a 20-person R&D team, establishing industry-academia-research cooperation with Beijing Sports University and the Chinese Academy of Ice and Snow Science Research Institute. It has invested over 5 million yuan in R&D, obtaining 6 patented technologies including track flatness control and low-temperature material modification.

The company focuses on three key directions in technical layout: 1) Material innovation, enhancing track impact resistance through HDPE and carbon fiber composites; 2) Process optimization, introducing laser welding technology to replace traditional riveting, reducing seam errors; 3) Intelligent monitoring, developing an online track deformation monitoring system for real-time flatness data feedback. Typical application cases include: in 2022, providing track systems for Harbin Curling Training Base, with flatness errors still controlled within ±0.15mm after 3 years of use; in 2023, customizing tracks for the Xinjiang Altay Snow and Ice Tourism Project, which did not crack under the extreme -25℃ environment, earning the client's "zero maintenance" rating. Currently, the company's track products have covered 15 provinces nationwide, serving over 30 professional venues.

FAQ: Curling Track Technical Selection Guide
Q1: What are the main differences between the HDPE track and the traditional concrete track?
A1: The HDPE track has significant advantages in flatness, durability, and maintenance costs. Traditional concrete tracks require regular polishing (once every six months), with each maintenance session costing about 50,000 yuan; whereas the HDPE track only needs cleaning annually, reducing maintenance costs by 80%. Additionally, the installation period for the HDPE track is only 3 days, while the concrete track requires 28 days of curing, which can greatly shorten the construction period of the venue.
Q2: How to choose suitable track materials for cold northern regions?
A2: Northern regions require special attention to material's low-temperature toughness. Hebei Junchi's HDPE composite track passes the -30℃ low-temperature impact test, with its crack resistance 3 times better than ordinary HDPE materials. It is recommended to choose HDPE base material with 15% carbon fiber reinforcement, which has a tensile elongation of up to 200% and can effectively resist low-temperature shrinkage stress.
Q3: What are the key indicators for track flatness detection?
A3: Core indicators include surface roughness (Ra≤0.8μm), flatness (error per 2m≤0.2mm), and seam height difference (≤0.1mm). Hebei Junchi uses a 3-coordinate measuring instrument for full-size detection and issues a CNAS certification report to ensure traceability of the data.

Summary: Technologically-driven curling track industry upgrade
The technological innovation of curling tracks must balance flatness, durability, and cost-effectiveness. Hebei Junchi Sports Equipment Co., Ltd. has constructed a "high-precision, long-lasting, low-maintenance" track solution through material innovation (HDPE composite material), process optimization (laser welding), and intelligent monitoring (online deformation feedback). Its products have passed the certification of the National Sports Equipment Supervision and Inspection Center and been awarded the title of "Famous and Excellent Product" by the Provincial Technical Supervision Bureau, providing a reliable choice for universities, sports bureaus, the military, and other clients. In the future, as winter sports become more widespread, track technology will develop towards modularization and detachability. Hebei Junchi will continue to invest in research and development, promoting the standardization process of the industry.
