Our Story
Built on Trust. Built to Last.
Golden Epic Manufacturers and Co was founded with a single conviction — that India's builders deserve a smarter, stronger, and more sustainable wall solution. Today, Gemco AAC Blocks are trusted by contractors, architects, and developers across Tamil Nadu.
Who We Are
Gemco was established in Thirukanurpatti, Thanjavur — the heart of Tamil Nadu's construction belt — to bring world-class Autoclaved Aerated Concrete technology within reach of every builder in the region.
Our manufacturing facility combines precision engineering with rigorous quality control, producing AAC blocks that consistently exceed IS 2185 Part 3 standards. Every block that leaves our plant is a promise of strength, accuracy, and reliability.
From small residential homes to large commercial complexes, Gemco products have been specified and trusted on hundreds of projects. We don't just supply materials — we partner with builders to ensure every project is delivered on time, on budget, and to specification.
Mission & Values
To manufacture and deliver the highest quality AAC building products that help India build faster, greener, and stronger — while making every customer feel supported at every step.
Trust
We say what we do and do what we say. Our customers rely on us for consistent quality and honest dealings.
Strength
Our products are engineered to perform. Every block is tested, every batch is certified, every delivery is dependable.
Thrift
We help builders save — on material costs, labour time, and energy bills — without ever compromising on quality.
Why AAC Blocks?
Autoclaved Aerated Concrete is the construction material of the future — and the present.
Larger block size and precise dimensions mean walls go up faster with less cutting and waste.
Reduces structural load, enabling leaner RCC frames and lower foundation costs.
Keeps interiors cooler in summer and warmer in winter, cutting air-conditioning costs.
Every batch manufactured and tested to BIS IS 2185 Part 3 standards.
How We Make It
Our manufacturing process is designed for precision, consistency, and scale.
Raw Material Selection
Fly ash, cement, lime, gypsum, and aluminium powder are sourced and tested to strict specifications before entering production.
Slurry Mixing & Casting
Ingredients are precisely proportioned, mixed into a slurry, and poured into moulds where the aluminium powder reacts to create millions of tiny air pores.
Pre-curing & Wire Cutting
The green cake is pre-cured until firm, then wire-cut to exact dimensions with tolerances of ±1.5mm — far tighter than conventional brick.
Autoclave Curing
Blocks are steam-cured in high-pressure autoclaves at 180°C for 8–12 hours, developing their final strength and dimensional stability.
Quality Testing & Dispatch
Every batch undergoes compressive strength, density, and dimensional checks before palletising and dispatching to site.
Quality & Certifications
Our commitment to quality is backed by independent testing and industry certification.
IS 2185 Part 3
Bureau of Indian Standards specification for Autoclaved Aerated Concrete blocks — the benchmark for AAC quality in India.
Compressive Strength Testing
Every production batch is tested for compressive strength at our in-house lab and by third-party accredited laboratories.
Dimensional Accuracy
Blocks are checked for length, width, height, and squareness to ensure consistent mortar joints and plumb walls.
Dry Density Verification
Density is verified to confirm thermal and acoustic performance meets specification for each grade supplied.
