Revolution! This Formwork Cuts Weight by 30% and Saves Huge Costs

ANHUI, China – April 30, 2026

  The construction formwork market is witnessing remarkable changes lately. More and more builders are turning to magnesium alloy formwork. Compared with traditional aluminum formwork that has dominated the industry for decades, this new lightweight material delivers better efficiency, eco-friendly performance and cost benefits for construction projects worldwide.

  The core innovation comes from a composite formwork system created by Anhui Magnesium-Aluminum Building Formwork Technology Co., Ltd., an affiliate of Baowu Magnesium Industry. It adopts a design of 70% magnesium standard panels plus 30% aluminum non-standard panels, cutting total weight by over 30%. For common 30-storey residential buildings, a standard aluminum panel weighs 25 to 30 kilograms, while the new composite panel only reaches 17 to 21 kilograms.

  Such a big weight difference brings huge improvements to daily construction work. Single workers are able to move and install the panels on their own, so teams no longer need extra staff for lifting work. This greatly eases physical workload on site. Meanwhile, lighter panels help make better use of storage areas and speed up installation and dismantling work, which effectively keeps projects running on track.

All these practical advantages are backed by real production data from Baowu Magnesium's manufacturing plant in Nanjing. As one of the world's leading production bases for magnesium alloy formwork, the facility produces 30,000 tons of magnesium-aluminum alloy components annually, including 20,000 tons of pure magnesium alloy products.

 

 

High manufacturing cost used to hold back the wider use of magnesium alloy formwork. Today, advanced automated production has changed this situation completely. The Nanjing plant is equipped with a 2700-ton die-casting machine and four robotic production lines, covering all procedures from raw material processing to die-casting, trimming and quality checks.

  Thanks to automation, each production line only needs one operator now, down from four previously. The time spent on making one panel has also been shortened from 100 seconds to 75 seconds, with more consistent product quality. The factory's exclusive automatic magnesium melt supply system, the first of its kind across the globe, cancels many unnecessary steps such as ingot processing and repeated melting. This optimizes the whole production chain, bringing lower costs, less carbon emission and more stable finished products.

  Around the world, the construction industry is moving toward green and sustainable development. In China, new guidelines for green building materials have been carried out in 101 cities, requiring qualified eco-friendly materials for government projects. Light weight, recyclability and low carbon footprint make magnesium alloy formwork fully meet these requirements.

  Industry practitioners point out that switching to this material helps projects adapt to updated purchasing standards. Contractors and developers who start using it early will gain an edge amid the growing demand for sustainable construction solutions.

  This new material has also gained wide recognition within the trade. In November 2023, Anhui Magnesium-Aluminum Building Formwork Technology Co., Ltd. was named one of China's Top 100 Enterprises in the formwork and scaffolding sector.

  Technical research jointly completed by enterprises and universities has also claimed top industry awards. The related high-toughness magnesium alloy casting technology can even be applied in automobile and aerospace fields. Researchers have also developed extra-large magnesium alloy components, which are 32% lighter than aluminum parts and ideal for large and complex building structures.

Now the whole industry is faced with rising labor expenses, tight construction schedules and stricter environmental requirements. Magnesium alloy formwork stands out as a practical alternative to traditional aluminum products. With proven performance, more affordable prices and strong policy support, it is set to lead new development trends in the global formwork industry.

  It is clear that replacing aluminum formwork with magnesium alloy products is not just a temporary trend. A brand new upgrade wave has already swept across the construction sector.
