Our Core Values
The principles that guide every decision we make — from raw material selection to final installation.
Precision Engineering
CNC-machined profiles and hardware tolerances measured in microns. Every cut, every joint, every weld is held to an exacting standard no competitor can match.
Uncompromising Quality
Premium ALMAX aluminium profiles, imported hardware, and multi-stage QC at every production step. We sign off on nothing we would not install in our own homes.
Client-First Partnership
We listen before we measure. Every project starts with a consultation to understand your vision, and ends with a handover you can trust — backed by warranty.
Innovation by Design
From curtain wall systems to slim-profile sliding doors, we stay ahead of architectural trends and bring international design standards to every Sri Lankan project.
Why We Choose ALMAX
ALMAX is Sri Lanka's benchmark aluminium profile system — and Greentek is an authorised fabricator. Here's what that means for your project.
Superior Strength-to-Weight Ratio
ALMAX profiles deliver structural rigidity with minimal visual bulk — ideal for large glazed facades and slim sightlines.
Precision Extrusion Tolerances
Consistent wall thickness and dimensional accuracy across every batch means joints are tight, seals are reliable, and finishes are flawless.
Imported Premium Accessories
All hardware — rollers, locks, hinges, seals — is sourced from trusted international suppliers and tested for Sri Lanka's tropical climate conditions.
Powder-Coated for Decades
Our electrostatic powder-coat finish bonds at the molecular level — UV-resistant, corrosion-proof, and available in any RAL colour with 20+ year retention.
High-Performance Glazing Options
Single, double, tinted, tempered, or laminated glass — matched to your thermal, acoustic, and safety requirements.
Weather-Tight Engineering
Multi-point gasket systems and drainage channels eliminate water infiltration, even in Sri Lanka's heaviest monsoon conditions.
