After launching an 180,000 m³ particleboard line with Shandong MINGHUNG in 2017, Qiaojia New Materials commissioned a 200,000 m³/year Laminated Strand Board (LSB) production line in March 2019. This milestone established Qiaojia as China’s first mass producer of LSB, with a complete portfolio spanning homogeneous, super-strength, and OSB boards – consolidating its position as the industry’s most diversified player.
Amidst Linyi’s 2019 mandate to eliminate 2.1 million m³ of backward capacity (5% of total output) and shut down 350 polluting mills:
Policy Shift: The government prioritized industrial park consolidation, favoring intelligent, eco-friendly projects；
Market Opportunity: Qiaojia’s LSB line filled the gap for premium boards, leveraging its state-owned backing (Linyi City Investment Group + Kaiyuan Wood) and dual safety certification (Shandong’s only panel manufacturer certified)；
Survival Edge: While 400+ mills faced forced closures due to steam supply cuts, Qiaojia maintained full operations through strict environmental compliance.
Product Innovation
Superior Strength: 2x higher MOR (modulus of rupture) than conventional particleboard, 40% improved screw-holding capacity；
Eco-Certified: MDI-based zero-added-formaldehyde technology, achieving ENF grade (China’s strictest standard)；
Climate Resilience: Waterproof additives enable use in arid Northwest China and humid coastal regions.
Intelligent Production Line
Core Equipment: Full-line import from Italy’s PALL Srl, featuring directional strand alignment and continuous press；
Digital Control: Real-time monitoring of 12 parameters via ShandongMINGHUNG’s IoT platform, reducing deviation to ≤0.1mm；
Efficiency Gains: Commissioned in 12 months (30% faster than industry average), with 98.5% yield from startup.
With LSB supplying Haier, Vanke, and Zhongyi Cabinets, and exporting to Europe/Africa, Qiaojia aims to：
1. Triple Capacity: Launch Phase III (300,000 m³) by 2025, targeting 900,000 m³ total output；
2. Global Branding: Expand through CCTV ads and international expos (e.g., Beijing International Home Show)；
3. Vertical Integration: Partner with furniture makers for “substrate + surface finishing” integrated solutions.
