Glued Laminated Timber (Glulam) Grading and Testing Requirements

Lam stock grading and testing are critical factors affecting the structural strength of glulam components. Our grading process combines two established methods:

• 1. Visual Grading: Experienced technicians assess each lam stock for natural characteristics and defects

• 2. Mechanical Grading: Advanced equipment measures mechanical properties including:

  • - Modulus of Elasticity (MOE)
  • - Strength characteristics
  • - Density profiles

Material Specifications:

• Base Materials: Multiple wood species available, Larch, Pinus Sylvestris, Japanese Cedar and Chinese Cedar;
• Strength Properties: Meet both European (EN) and American (APA/ANSI) glulam grading standards
• Quality Assurance: Continuous monitoring throughout production process

Production Process

• 1. Combined visual and mechanical grading
• 2. Optimized lam stock arrangement
• 3. Precision gluing and pressing
• 4. Final quality inspection
