For contractors, builders, and site engineers, choosing the right shuttering material can have a direct impact on construction quality, labour requirements, project timelines, and overall cost. Traditional plywood has been widely used for concrete formwork, but repeated exposure to moisture and demanding site conditions can cause swelling, edge damage, warping, and deterioration. As a result, contractors are increasingly exploring durable composite alternatives that can withstand repeated concrete pours while delivering consistent surface quality. One such option is the PAC® Shuttering Board, a polymer-composite formwork board designed as an alternative to conventional plywood and other formwork materials. At Rajratan Industries Private Limited, the PAC® Shuttering Board range includes the ECOPRIME Standard and ECOPRIME Premium grades, along with an 18mm heavy-duty option for applications requiring additional stiffness. But which one should you choose? The answer depends on your project type, expected repetitions, handling conditions, and structural requirements. What Is a PAC® Shuttering Board? A PAC® Shuttering Board is a composite formwork sheet made using industrial-grade plastic materials reinforced with aluminium oxide, fibres, and XLP metals. The board is designed for concrete formwork applications where resistance to moisture, repeated handling, and consistent surface performance are important. Unlike conventional plywood, the PAC® board is designed to be resistant to water, termites, rot, and common moisture-related problems. Its non-absorbent surface also helps maintain a more consistent formwork condition during concrete casting. Another important feature is Rajratan's 40% buyback program, through which used PAC® boards can be returned and their value adjusted against the purchase of new boards, subject to the applicable buyback terms. This creates an opportunity to recover part of the material value at the end of its service life instead of treating the used board simply as construction scrap. ECOPRIME Standard vs ECOPRIME Premium Both ECOPRIME Standard and ECOPRIME Premium are designed for concrete formwork, but they are intended for different levels of usage. Technical Feature ECOPRIME Standard ECOPRIME Premium 18mm Heavy-Duty Colour Marble White Marble Black Marble Black / Grey Standard Thickness 12 mm 12 mm 18 mm Sheet Size 8 ft × 4 ft 8 ft × 4 ft 8 ft × 4 ft Expected Repetitions 30–40 runs 60–100+ runs 80+ runs Density 1100 kg/m³ 1320 kg/m³ 1320 kg/m³ Approx. Sheet Weight 40 kg 45 kg 62 kg Best Suited For Residential and low-rise projects Commercial, high-rise and repeated-use projects Heavy RCC applications The right choice therefore depends less on simply comparing the purchase price and more on how many times the board will be used and the type of concrete work involved. ECOPRIME Standard: A Practical Choice for Regular Construction ECOPRIME Standard is a 12mm marble-white PAC® Shuttering Board designed for projects requiring reliable performance with a moderate number of repetitions. With an approximate density of 1100 kg/m³ and a weight of around 40 kg per 8 × 4 ft sheet, it is comparatively easier to handle at the construction site. It is particularly suitable for: Residential buildings Low-rise commercial projects Slabs and beams Columns Projects where 30–40 repetitions are sufficient For contractors working on smaller or medium-sized projects, Standard can offer a practical balance between initial investment, handling, and expected service life. Understanding the Cost Per Use Based on the figures in the product specifications: Approximate price: ₹2,560 per 8 × 4 ft sheet Expected usage: up to around 40 repetitions Approximate cost per use: ₹64 per repetition With the applicable 40% buyback arrangement, the effective cost can reduce further depending on the final buyback value and purchase terms. This is why evaluating shuttering material purely on its initial purchase price can be misleading. The more useful metric is often cost per concrete pour or cost per repetition. ECOPRIME Premium: Designed for Higher Repetition and Demanding Projects ECOPRIME Premium is a 12mm marble-black PAC® Shuttering Board designed for applications where higher repetition and greater board density are important. With a density of approximately 1320 kg/m³ and a sheet weight of around 45 kg, Premium is designed for more demanding formwork applications. It is suitable for: Commercial construction High-rise buildings Large residential projects System formwork Projects requiring frequent reuse Applications where consistent board performance over multiple cycles is important The Premium grade is designed to deliver approximately 60–100+ repetitions, depending on factors such as framing, handling, cleaning, storage, and site practices. Cost Per Repetition Using the stated product figures: Approximate price: ₹2,880 per 8 × 4 ft sheet Example usage: 80 repetitions Approximate cost per repetition: ₹36 This demonstrates an important point: a board with a higher initial price can potentially provide a lower cost per use when it achieves significantly more repetitions. For contractors handling large projects, this can make the Premium grade a more economical option over the complete project lifecycle. Standard vs Premium: Which PAC® Board Should You Choose? There is no single answer for every construction project. The better choice depends on three key factors. 1. Project Size and Construction Timeline For residential houses and low-rise construction where the number of required repetitions is relatively moderate, ECOPRIME Standard can be a practical choice. For high-rise buildings, commercial projects, and projects involving repeated formwork cycles, ECOPRIME Premium may be more suitable because of its higher density and higher expected repetitions. 2. Site Handling Conditions The way shuttering boards are handled has a major impact on their service life. Boards that are properly cleaned, stored, handled, and installed can generally provide better long-term performance. If your project has frequent shuttering cycles and proper site supervision, investing in a higher-performance board can make sense. For projects with moderate usage, Standard can provide a more economical starting point. 3. Type of Structural Work For standard slabs, beams, and columns, a 12mm PAC® Shuttering Board may be suitable depending on the formwork design and support arrangement. For applications involving heavier RCC sections, retaining walls, bridge-related structures, or situations requiring additional stiffness, the 18mm heavy-duty board can be considered. The final thickness and support arrangement should always be selected according to the structural and formwork requirements of the project. How to Get Better Performance from PAC® Shuttering Boards Even a durable shuttering board needs proper handling to achieve its expected service life. Use Appropriate Nails and Screws PAC® boards can be cut, nailed, screwed, and drilled using commonly used carpentry tools. When nailing, avoid placing nails too close to the edge. Maintaining an appropriate edge distance helps reduce the possibility of damage during installation. Use the Right Cutting Tool A standard circular saw can be used for cutting the boards. A suitable blade with approximately 40–60 teeth can help produce a cleaner edge. Apply Shuttering Oil Correctly PAC® boards do not require the same level of oiling as conventional plywood. A light and even application of suitable shuttering oil can help make de-shuttering easier and keep the board surface cleaner. Maintain Proper Support Spacing The support system below the shuttering board plays an important role in controlling deflection. For the support arrangement mentioned in the product guidelines, runners can be maintained at approximately 12 inches centre-to-centre, subject to the formwork design and load requirements. Proper support is particularly important when working with wet concrete because the pressure exerted on the formwork can be significant. PAC® Shuttering Board vs Traditional Plywood The biggest difference between the two materials is not simply the purchase price. It is the way the material behaves over repeated cycles. Plywood can be affected by moisture, swelling, edge damage, warping, and deterioration with repeated use. PAC® Shuttering Board is designed to address these issues through its composite construction and moisture-resistant properties. However, the actual economics of any shuttering material depend on several factors: Purchase price Number of repetitions Labour requirements Handling losses Surface finish Cleaning and maintenance Transportation End-of-life value Therefore, contractors should compare total cost of ownership, rather than looking only at the initial price per sheet. Trial Before Bulk Purchase For contractors considering PAC® Shuttering Boards for the first time, starting with a smaller trial quantity can be a practical approach. A trial order of 5–10 sheets allows the site team to evaluate: Cutting Nailing and screwing Handling De-shuttering Concrete surface finish Cleaning Repetition performance Once the board has been tested under actual site conditions, the contractor can decide which grade is better suited to the project before moving to larger quantities. Ordering and Logistics Rajratan supplies PAC® Shuttering Boards to customers across India. For standard orders, the stated payment structure is 30% advance and 70% balance before dispatch, while transportation is handled through third-party logistics providers. For smaller trial orders, delivery may be arranged through the transporter's nearest godown, while larger orders can be delivered to the project site depending on logistics and location. Customers should confirm current pricing, availability, transportation charges, payment terms, and delivery conditions with Rajratan before placing an order. Frequently Asked Questions Will PAC® Shuttering Board crack during normal site handling? PAC® Shuttering Boards are designed to be impact-resistant and suitable for regular construction-site handling. However, like any formwork material, unnecessary throwing, dropping, or improper handling should be avoided. Can PAC® Shuttering Board be cut and nailed like plywood? Yes. The board can be cut, nailed, screwed, and drilled using commonly used carpentry tools. How does the 40% buyback program work? Under the applicable buyback program, used PAC® boards can be returned and the eligible value can be adjusted against the purchase of new boards. Contractors should confirm the current buyback terms and conditions with Rajratan before purchase. Which is better: ECOPRIME Standard or Premium? ECOPRIME Standard is suited to projects requiring moderate repetitions and a more economical initial investment. ECOPRIME Premium is better suited to projects where higher repetitions, higher density, and long-term reuse are priorities. For heavy RCC applications, the 18mm option can be considered where additional stiffness is required. How many times can a PAC® Shuttering Board be reused? The expected repetitions vary by grade: ECOPRIME Standard: approximately 30–40 repetitions ECOPRIME Premium: approximately 60–100+ repetitions 18mm Heavy-Duty: approximately 80+ repetitions Actual performance depends on installation, support spacing, cleaning, handling, storage, and overall site conditions. Final Verdict: Choose Based on Usage, Not Just Price The right shuttering board is the one that delivers the best balance between initial investment, repetitions, handling, surface finish, and overall project requirements. For smaller residential and low-rise projects, ECOPRIME Standard provides a practical option for moderate reuse. For commercial, high-rise, and high-repetition projects, ECOPRIME Premium offers a higher-performance alternative designed for extended reuse. And when the application demands additional thickness and stiffness, the 18mm heavy-duty PAC® Shuttering Board can be considered. Before making a bulk purchase, evaluate the board on your actual site conditions and calculate the cost per repetition. That gives a much clearer picture of the real economics of your shuttering material. Looking for the right PAC® Shuttering Board for your project?
