Choosing between Premium form plywood and Promax form plywood is a critical decision for contractors who care about reuse cycles, surface quality and overall project cost. This plywood grade comparison explains key technical differences and helps you match the right grade to each concrete formwork project.
Overview of Premium and Promax Formwork Plywood
In the FOMEX GLOBAL formwork range, Premium form plywood is designed as a high-quality, multi-use solution for demanding projects, while Promax form plywood represents the highest-performing grade, engineered for maximum reuse cycles and harsh jobsite conditions.
Both grades are film-faced panels built for concrete formwork, but they differ in glue content, boiling hours, film performance and target reuse ranges. Understanding these differences helps contractors and importers make smarter decisions on grade selection instead of relying on price alone.
A clear plywood grade comparison between Premium and Promax gives project managers and buyers a common language to discuss expectations around stiffness, surface quality, reuse cycles and risk control on site.
Technical Comparison: Premium vs Promax Formwork Plywood
The table below summarises key parameters for the two grades. Exact values depend on specification, but the relative positioning remains the same: Promax is optimised for higher durability and reuse potential.
| Parameter | Premium Form Plywood | Promax Form Plywood |
|---|---|---|
| Typical glue system & boiling hours | WBP melamine with high glue content, medium–long boiling hours for strong bond durability | WBP melamine or phenolic with very high glue content, longest boiling hours for maximum bond strength |
| Film type and weight | High-quality film faced plywood for smooth concrete finish and good wear resistance | High-quality film, often with higher wear resistance for longer life under intense use |
| Core quality and construction | Selected veneers with controlled core gaps, good balance between cost and performance | Carefully selected veneers, tighter control of core gaps and veneer structure for maximum stability |
| Expected reuse range* | Up to 12 uses with proper handling | Up to 20 uses with proper handling |
| Moisture resistance and stability | Strong resistance suitable for multi-cycle formwork in most climates | Enhanced resistance for more cycles and tougher climates, especially under repeated wet–dry cycles |
*Actual reuse cycles depend on glue type, project design, release agents, stripping methods, storage and climate conditions.
Choosing by Project Type and Budget
A smart plywood grade comparison considers not only technical data but also project duration, budget and reuse expectations. The “best” grade is the one that delivers the lowest risk and best cost-per-use for your specific job.
Short-Term Projects with Lower Reuse Targets – When Premium Is Sufficient
For short-duration projects, small commercial jobs or residential structures with moderate pour cycles, premium form plywood usually provides more than enough performance. It offers a robust film surface, good bond strength and stable cores at a price point that fits tighter budgets.
When expected reuse cycles fall in the 8–12 range and the project is not exposed to extreme climates, Premium is often the most cost-efficient solution. Contractors still get reliable performance without paying for the extra margin designed into Promax.
Long-Term Projects or High-Reuse Requirements – When Promax Is Recommended
For long-term projects, high-rise towers, large infrastructure or contractors using systematic formwork operations across multiple sites, promax form plywood becomes the stronger choice. Its glue and film systems are designed to withstand frequent cycling, aggressive schedules and heavy vibration.
When targets are in the 15–20 reuse range, or when formwork is expected to move from one project to the next, Promax helps minimise panel replacement, reduce risk of failure and support more predictable formwork planning across the company.
Climate and Exposure Conditions
Climate plays a major role in determining how quickly panels degrade. In hot, humid, coastal or high rainfall environments, repeated wetting and drying plus high temperature can stress both glue lines and film. Promax, with its higher glue content and more robust film, is better suited for these harsh conditions.
In moderate climates where panels can be kept relatively dry and protected, premium form plywood can still reach its intended reuse range. Understanding local climate and jobsite storage conditions is key to making the right grade choice.
Cost per Use Analysis: Premium vs Promax
A simple cost-per-use calculation often shows that high-performance panels can save money over the full project, even if they cost more per sheet. The example below assumes proper handling and average jobsite conditions.
| Grade | Approx. Panel Cost | Typical Reuse Range | Estimated Cost per Use |
|---|---|---|---|
| Premium form plywood | 160 | ≈ 8–12 uses (assume 10) | ≈ 16 per use |
| Promax form plywood | 200 | ≈ 15–20 uses (assume 18) | ≈ 11 per use |
Over a 6–12 month project with many pours, the lower cost-per-use of Promax can offset its higher initial price, particularly when labour, downtime and claims from panel failure are included. For shorter projects with fewer cycles, Premium may still be the more economical option.
Decision Matrix for Contractors
The following points help contractors decide which grade to specify based on company profile, project type and risk tolerance.
Small vs Large Contractors
- Small and mid-size contractors: Often prioritise cash flow and prefer premium form plywood for its lower upfront cost and solid performance on individual projects.
- Large contractors and formwork specialists: Usually manage panels across multiple sites and benefit more from promax form plywood with higher reuse and better predictability.
Domestic vs Export-Funded Projects
- Domestic projects: Premium is frequently sufficient when specifications are flexible and finish requirements are standard.
- Export-funded or international standard projects: Promax is often preferred to meet stricter requirements on concrete finish, safety margins and documentation.
Safety and Quality Expectations
- Projects with demanding safety requirements, heavy loads or complex geometry benefit from the extra margin built into Promax.
- Where budgets are tight but reuse targets are moderate, Premium provides a strong compromise between performance and cost.
How FOMEX GREENWOOD Supports Grade Selection
Selecting between premium form plywood and promax form plywood is easier when you have access to technical support. FOMEX GREENWOOD engineers can review structural drawings, formwork layouts and reuse targets to recommend the most suitable grade and thickness.
Sample panels and trial pours can be arranged for key customers who want to validate performance before large-scale deployment. This approach reduces risk, aligns expectations and provides real data for your internal plywood grade comparison and procurement decisions.

FAQs
What is the main difference between Premium and Promax plywood?
The main difference lies in reuse potential and durability. Premium form plywood is engineered for strong multi-use performance, while promax form plywood uses higher glue content, more robust film and tighter core control to support significantly higher reuse cycles and tougher jobsite conditions.
Is Promax always the better choice for high-rise projects?
Promax is often the preferred choice for high-rise projects because of its higher reuse potential and safety margin. However, if certain elements have low reuse counts or less demanding loads, Premium may still be suitable for those specific areas, depending on your formwork design.
How do I justify the higher cost of Promax to my client?
You can demonstrate that although Promax has a higher panel price, its lower cost-per-use, reduced replacement needs and lower risk of surface defects often decrease the total cost of concrete works. Including labour, delay and quality repair savings in your calculation makes the value of Promax clear.
Can I mix Premium and Promax in the same project?
Yes. Many contractors use premium form plywood for less critical or low-reuse elements and reserve promax form plywood for high-reuse zones such as core walls, main slabs or repeating structural bays. Mixing grades strategically can optimise both performance and budget.
