A well-controlled production process is the foundation of a high-performance glass system.
At Mannlee, our precision-driven workflow ensures consistent quality, structural integrity, and safety in every panel we produce.
From raw materials to final inspection, we focus on delivering reliable, project-ready glass solutions that meet international standards and client expectations.
We source all raw materials—including tested glass, aluminum profiles, and hardware—from long-term, trusted suppliers who meet strict quality and environmental standards.
Our supplier evaluation system ensures transparency, sustainability, and regulatory compliance, allowing us to maintain consistent material quality and reliable supply for every project.
Glass sheets are precisely cut using CNC-controlled machines to match each project’s specifications.
We perform edge grinding, polishing, or beveling to ensure safety, clean lines, and a refined appearance.
Every panel is carefully handled to prevent stress points and to prepare it for tempering, laminating, or direct assembly—guaranteeing both performance and aesthetics.
Aluminum and stainless steel profiles are cut, punched, and processed with high precision to match structural and design specifications.
We apply surface treatments such as powder coating, anodizing, or brushing to enhance durability and visual appeal.
Each frame component is quality-checked to ensure proper fit, corrosion resistance, and long-term stability in various environments.
All hardware components—such as brackets, fasteners, connectors, and locks—are carefully selected and prepared according to each system’s design.
We perform compatibility checks to ensure seamless integration during assembly.
By pre-sorting and verifying every part in advance, we reduce on-site errors, speed up installation, and guarantee long-term performance and safety of the entire system.
Glass panels, frames, and hardware are assembled by trained technicians using standardized procedures to ensure accuracy and structural integrity.
Each unit is aligned, secured, and tested for stability and functionality.
Our precise assembly process minimizes installation time on site, reduces adjustment needs, and ensures that every system is ready for seamless integration into your project.
Each unit undergoes a thorough inspection and testing process before final packaging.
We check dimensions, edge quality, surface clarity, and system fit to ensure they meet design and safety standards.
Additional testing—including impact resistance, thermal stability, and load-bearing performance—is conducted where required, guaranteeing consistent, defect-free products ready for reliable installation.
Before leaving our facility, every glass system is thoroughly cleaned, inspected, and protected.
We remove dust, residues, and handling marks to ensure a flawless appearance.
Each unit is then packed using export-grade materials—complete with corner guards, cushioning, and clear labeling—to prevent damage during transport and ensure safe, installation-ready delivery.

Toughened glass and tempered glass are the same safety glass, made stronger by heat treatment, with differences mainly in naming and regional usage.
Glass spontaneous breakage occurs when tempered glass shatters without impact, often caused by nickel sulfide inclusions, thermal stress, or edge damage.
