A Milestone in Engineered Timber Excellence

We are proud to announce a significant achievement that places Buana Triarta at the forefront of the global timber manufacture industry: our Keruing glulam has been certified to GL20 grade by the Glued Laminated Timber Association of Australia (GLTAA), the highest grade in their current classification system. This certification represents not just a technical accomplishment, but a commitment to delivering unparalleled strength and reliability in glue laminated timber for structural applications worldwide.

According to the GLTAA, their grading system now ranges from GL8 to GL20, with each grade representing a specific set of mechanical performance characteristics. Achieving the GL20 grade signifies that our products meet the most demanding requirements for stiffness and load-bearing capacity in the market.

Understanding the GL20 Standard: What It Means for Your Projects

The GL20 certification is more than a label, it's a guarantee of performance. For our clients, this translates to:

- A Modulus of Elasticity (MOE) of 20,000 MPa, ensuring exceptional stiffness and minimal deflection under load

- Consistent, verified structural properties across every beam and component

- Reliability for the most demanding architectural and engineering applications

This makes our Apitong glulam ideal for long-span beams, heavy-load structures, and international standard projects where structural integrity cannot be compromised.

_{Why GL20 Matters for International Projects}

As the first Indonesian hardwood manufacturer to achieve GL20 certification for Keruing glulam, we bridge the gap between premium tropical hardwoods and international engineering standards. This certification:

1. Provides engineers and architects with verified data for structural calculations
2. Ensures compliance with stringent international building codes
3. Offers peace of mind for projects requiring certified material performance

Our glulam now carries the same grade recognition as the world's leading engineered timber products, while offering the unique benefits of tropical hardwood.

Our Journey to GL20 Certification

The path to GL20 certification required rigorous testing, process refinement, and unwavering commitment to quality. Through controlled manufacturing processes and selective sourcing of Apitong wood, we have demonstrated that Indonesian hardwoods can achieve and exceed global standards for glue laminated timber.

This achievement reflects our dedication to advancing the capabilities of tropical timber in structural applications, providing architects and engineers with new possibilities for sustainable construction.
