The rising cost and limited reusability of timber in construction have necessitated innovative alternatives. One such solution is metallic steel fabricated sheets, designed to replace traditional timber “Kirundu” for shuttering during the casting of in-situ reinforced or plain concrete structures.
Steel formwork is a type of steel decking used in construction projects to support wet concrete. Due to its durability and strength, it is widely used in buildings, bridges, dams, and retaining walls. This alternative has proven to be cost-effective, time-saving, and capable of producing high-quality concrete finishes.
Our pricing is based on square meter coverage, with minor extensions and cantilevers covered free of charge. Additionally, our team collaborates with the shuttering crew on-site to ensure knowledge sharing while keeping all workers actively engaged.
When incorporating steel sheets for shuttering, structural designers must account for the following loading considerations (measured in square feet):
(Loading considerations details can be added as required by the design standards.)
Advantages of Steel Formwork Over Timber
• Environmental Conservation – No trees are cut, reducing deforestation.
• Time Efficiency – Steel sheets are quicker to install compared to timber formwork.
• Neater Concrete Finish – The sheets provide a smooth and uniform surface, minimizing the need for post-casting finishing.
• No Honeycombing – The formwork ensures compact and well-formed concrete structures.
• Minimal Joint Gaps – This reduces the loss of flowable fill, improving concrete integrity.
• Easy Installation – Workers can quickly master the skill of installing metallic formwork.
• Moisture Resistance – Unlike timber, steel does not absorb moisture, preventing premature drying and ensuring proper concrete curing.
• Shape Retention – Steel formwork does not shrink or deform, maintaining the intended shape of the cast structure.
Challenges and Solutions
SN | Challenge | Solution |
1. | Theft Risk at insecure sites | Shared responsibility between the contractor, client, and subcontractor to secure the site. Costs may be shared if losses occur. |
2. | Difficulties in Non-Square Structures | Small timber pieces are used to fill gaps where necessary. |
3. | Varying Floor Heights | Additional poles at regular intervals help accommodate different height requirements. |
4. | Reduced Demand for Timber | Continuous sensitization efforts highlight the environmental and cost benefits of metallic formwork. |
5. | Traditional Mindset in the Construction Sector | Awareness campaigns to educate industry players on the advantages of steel formwork over timber. |

The adoption of metallic formwork sheets in construction presents an innovative, cost-effective, and environmentally sustainable alternative to traditional timber shuttering. Despite challenges such as theft risks and structural variations, practical solutions exist to ensure seamless integration into modern construction practices.
As the industry shifts toward greener and more durable building methods, steel formwork stands out as a reliable and efficient choice for both large- and small-scale projects.
