Is Your Old Wood Infill Making Your Horses Sick?
Old or improperly sourced wood infill can expose horses to toxins, mold, and high ammonia levels, leading to serious health issues like laminitis and respiratory disease. Switching to non-porous, engineered materials eliminates these risks, protecting animal welfare and reducing operational liability for facility owners.
Traditional wood stall walls seem like a natural choice, but they can hide significant health risks that affect both horses and stable operators. Porous, aging wood creates an environment where toxins, bacteria, and respiratory irritants can thrive, leading to increased vet bills and potential liability for your business.
The Danger of Toxic Wood Species
Not all wood is safe for equine environments. Certain species are highly toxic and can cause severe illness from simple contact. Black walnut, for instance, is extremely dangerous and can cause severe laminitis within hours, even if it only makes up a small percentage of the shavings or boards. Other woods like maple can also be toxic, while aromatic woods such as cedar can irritate a horse’s sensitive respiratory tract, leading to chronic breathing problems or allergic reactions.
Respiratory Risks from Ammonia and Mold
Over time, wood boards absorb urine and moisture. This creates a perfect breeding ground for mold and bacteria deep within the planks where surface cleaning can’t reach. As the organic material and urine decompose, they release high concentrations of ammonia gas. This airborne irritant is a well-documented cause of respiratory inflammation and disease in stabled horses. Poor air quality not only impacts animal health but also creates an unhealthy working environment for stable staff.
Identifying Safer Infill Solutions
Protecting horses and your clients’ investment starts with choosing the right materials. Modern, engineered infills are designed to eliminate the problems inherent in traditional wood.
- UV-Stabilized HDPE: Our 28-32mm High-Density Polyethylene planks are completely non-porous. They cannot absorb moisture or urine, which stops ammonia and mold growth at the source. This “Zero Maintenance” material is easy to sanitize, ensuring a hygienic environment and drastically reducing labor costs.
- High-Density Bamboo: As an alternative, our 28-38mm strand-woven bamboo offers incredible durability. With a Janka hardness over 3000 lbf, it is three times harder than oak and naturally resistant to mold and rot. It provides the classic look of wood without the health risks of softwoods.
By upgrading to these advanced infill options, distributors and project managers can offer a superior product that ensures animal safety, promotes long-term durability, and protects the health of valuable equine assets.
Why Does Bamboo Add Structural Stiffness to Old Frames?
Bamboo enhances the stiffness of structures through its unique internal composition. The material’s strength comes from its natural composite structure, where dense fibre sheaths and rigid cellulose microfibrils provide exceptional resistance to bending and deformation. This makes our high-density, strand-woven bamboo planks an ideal choice for reinforcing stable panels.
Microstructural Properties Driving Stiffness
The remarkable stiffness of bamboo originates from its internal architecture. It functions as a natural composite, with the arrangement of dense fibre sheaths around its vascular bundles providing the core of its strength. Within its cell walls, crystalline cellulose microfibrils create an incredibly rigid and strong foundation. Our high-density, strand-woven bamboo planks are engineered to leverage this advanced microstructure, delivering maximum durability and structural integrity for your stables.
Mechanical Performance Characteristics
On a mechanical level, bamboo outperforms many traditional materials. It has a higher modulus of elasticity than steel, allowing it to resist deformation and stretching more effectively. This makes it exceptionally good at handling bending loads. With a Janka hardness rating that exceeds 3000 lbf, our strand-woven bamboo is about three times harder than oak, providing a dense and durable barrier that withstands the rigors of equestrian environments.
Practical Structural Advantages
Using bamboo infill provides immediate structural benefits. The wide surface area of the planks distributes impact and pressure across the stable frame, which minimizes deflection and adds crucial stability. This is especially useful when retrofitting older structures. Because our bamboo is naturally resistant to mold and rot, it maintains these structural properties for years, protecting your investment and ensuring a safe environment for your horses.

Can You Install New Boards in Old Channels?
Yes, retrofitting older horse stalls with new infill boards is an effective way to upgrade your facility. The success of the project depends on the condition of the original steel frame. If the existing channels are structurally sound, straight, and free of significant rust or damage, you can replace old wood with modern materials like our HDPE or high-density bamboo.
Assessing Your Existing Stall Frame and Channels
Before ordering new infill, a thorough inspection of your existing stall structure is essential. Check the steel posts and channels for any signs of deep rust, corrosion, or physical damage that could compromise safety. It’s also important to confirm the frame is still plumb and the channels are straight. Warped or bent channels will make it difficult to install uniform, pre-cut planks like our zero-maintenance HDPE or kick-proof bamboo, which require a true fit for optimal performance.
The Retrofitting Process: From Old Wood to New Infill
Once you’ve confirmed the frame is sound, start by carefully removing the old wood boards. After the channels are clear, take precise measurements of the interior channel dimensions (length and depth) to ensure your new boards are cut to the correct size. The new HDPE or Bamboo planks should then slide smoothly into the channels, creating a snug and secure wall without excessive gaps that could cause rattling or create pinch points.
Ensuring a Safe and Secure Installation
A secure fit is critical for both durability and animal safety. If your system requires them, use high-quality fasteners like the 304 Stainless Steel screws included in our hardware kits to prevent rust streaks. Double-check that all boards are tightly fitted to eliminate rattling and maintain the wall’s structural integrity. Finally, ensure the bottom plank is installed with a minimal gap to the ground, adhering to our ‘Cast-Proof Design’ standard to prevent a horse’s hoof from getting trapped.
How Much Maintenance Will You Save (The 10-Year Math)?
Choosing a modern infill over traditional wood provides substantial long-term savings for your facility. By eliminating annual costs for sealing, painting, board replacement, and the associated labor, our systems protect your operational budget. This turns a recurring maintenance liability into a durable, long-term asset that keeps your stalls consistently safe and available.
Comparing Annual Costs: Wood vs. Zero-Maintenance Infill
Traditional wood infill creates a cycle of recurring expenses. Every year, you have to budget for the labor and materials needed to seal, paint, and replace boards that have been chewed, kicked, or damaged by moisture. These small but constant costs add up, eating into your profit margins over the life of the stable.
Our UV-stabilized HDPE infill offers a clear alternative with its ‘Zero Maintenance’ design. It completely eliminates the need for paint, sealants, or repairs from chewing and rot. For a more classic look, our high-density strand woven bamboo is naturally resistant to mold and rot. With a Janka hardness over 3000 lbf, it is three times harder than oak, dramatically reducing replacement frequency compared to softer woods like pine.
The 10-Year Projection for Material Replacement
The financial benefit becomes clear when you project costs over a decade. Simply multiply your estimated annual wood maintenance expenses by ten. Then, subtract the one-time initial investment for the HDPE or bamboo upgrade to see your net savings. This proactive investment is significantly more cost-effective than performing emergency repairs after a broken board compromises stall security.
Our stable systems are built for longevity. The entire steel frame undergoes hot-dip galvanization after fabrication, meeting the strict BS EN ISO 1461 standard. This process provides a protective zinc coating that is designed to last for decades, ensuring the structural frame will easily outlive the typical maintenance cycle of wood.
Factoring in Labor and Stall Downtime
Beyond materials, the biggest hidden cost of wood is labor and operational disruption. Upgrading to a maintenance-free infill eliminates the recurring hours your team spends sanding, painting, and fitting replacement boards. More importantly, it prevents costly stall downtime. A stall that’s out of commission for repairs is a stall that isn’t generating revenue or available for your training program. Our HDPE and bamboo systems ensure your stalls are always safe, functional, and ready for use.
Final Thoughts
Cheaper stalls often use pre-galvanized tubes, leaving welds exposed to rust from day one. Our strict “Hot-Dip After Fabrication” standard (ISO 1461) protects every edge and weld. This is the difference between a quick sale and a long-term, trusted supply partnership.
The next step is to verify our engineering in person. A small trial order allows you to assess the material quality and flat-pack system before committing to a full container. Contact our team to get a quote and discuss your OEM requirements.
Frequently Asked Questions
Why is “Hot-Dip Galvanized After Fabrication” so important?
This process is our core quality guarantee. We construct the entire stable panel from raw structural steel first, then immerse the completed structure in molten zinc. This method, certified to ISO 1461, seals every weld, corner, and edge against rust. Competitors often weld pre-galvanized tubes, leaving the critical weld points exposed and vulnerable to corrosion from the start. Our method ensures decades of structural integrity, dramatically reducing replacement costs and safety risks.
