About AATIS

Thailand's specification-grade aluminium composite panel, manufactured locally since 2003.

AATIS is a Thai-manufactured aluminium composite panel brand distributed by Maenum Group. Over more than two decades, AATIS panels have been specified by leading architects and contractors on landmark buildings across Thailand — from government complexes and transport infrastructure to high-rise commercial towers and hospitality projects. Every panel is produced at our facility on Bangna-Trad Road, Samut Prakan, and backed by internationally certified fire performance.

Our history

1988 Maenum Group established Maenum Group is founded in Thailand as an aluminium stockhouse serving the construction and architectural industries — building the distributor relationships and technical expertise that would underpin the AATIS brand.

2003 First ACP manufacturing line in Thailand MN Chai Corporation launches Thailand's first locally manufactured aluminium composite panel production line. AATIS is born — giving Thai architects and contractors a domestically produced, specification-grade alternative to imported ACP for the first time.

2005 Partnership with Dongbu Group AATIS enters a supply partnership with Dongbu Group (South Korea) for premium pre-coated aluminium coil — establishing the material quality standard that AATIS panels are built on.

2008 Partnership with Novelis Distribution partnership established with Novelis — one of the world's leading aluminium rolling companies — further strengthening AATIS's access to premium-grade aluminium alloy for panel production.

2020 International fire certifications — BS, DIN, ASTM AATIS/fr achieves a comprehensive stack of 10 internationally recognised fire test certifications, including BS 476 Class 0 (UK), DIN 4102 Class B1 (Germany), ASTM E84 Class A, UBC 26-9, and ASTM E119 2-hour fire resistance (USA) — qualifying AATIS/fr for the most demanding specification requirements across all major international standards.

2020 Krung Thep Aphiwat Central Terminal 200,000 sqm of AATIS/fr installed on Thailand's largest railway station and Southeast Asia's largest rail hub — the landmark project that defines the AATIS portfolio.

2022 Factory expansion — KM 23 facility MN Chai Corporation expands manufacturing to the current KM 23 facility on Bangna-Trad Road, Samut Prakan — increasing production capacity and consolidating operations at a purpose-built manufacturing site.

Our values

Quality Every AATIS panel is manufactured using premium-grade aluminium alloy from partners including Novelis and Dongbu Group, and backed by 10 internationally recognised fire test certifications. We do not compromise on material specification — because the buildings our panels go on cannot afford us to.

Service With over 35 years in the Thai construction industry, Maenum Group understands what architects, contractors, and project teams need — fast, reliable supply, accurate technical documentation, and support from specification through to installation. Local manufacturing means we can respond to project timelines that imported alternatives cannot.

Integrity We publish our fire test results in full, with downloadable reports from accredited laboratories. We do not overstate performance claims. The certifications we hold are the certifications that appear on our technical documentation — and the same ones that have qualified AATIS/fr for Thailand's most scrutinised public-sector projects for over two decades.
