190x65 Merbau Laminated GL17S Structural Beam

190x65 Merbau laminated (Glulam) beams are high-strength, Class 1 durable structural hardwood engineered to GL17 specifications, ideal for exposed, termite-resistant, and high-load applications. These beams offer superior stability, reduced warping, and a rich, reddish-brown aesthetic, with lengths available up to 6.0m or more. 

Key Features and Benefits

• Structural Grade (GL17): High structural strength (GL17S) suitable for demanding, long-span applications.
• Durability & Resistance: Class 1 durability rating, making them highly resistant to rot, termites, and harsh weather.
• Stability: Engineered for superior dimensional stability with reduced shrinking, twisting, or warping.
• Applications: Suitable for both interior and exterior use, such as decking beams, roof structures, lintels, and pergolas.
• Aesthetic Appearance: Features a distinct reddish-brown color, often with a premium A-grade appearance.
• Compliance: Generally manufactured to meet Australian standards (AS/NZS 1328).
