PAC® Shuttering Boards: Manufacturing Excellence Meets Monsoon-Proof Durability

Rajratan’s PAC® Shuttering Boards are engineered from 100% pure industrial-grade packaging waste (sourced from Patanjali, Nestlé production lines), reinforced with XLP fiber, metal dust powder, and aluminum oxide. Designed as a Reusable Construction Board, they offer zero water absorption, 22.0 N/mm² compressive strength, and 0.33–0.64% moisture content stability, helping eliminate warping, swelling, and secondary plastering rework in India’s demanding monsoon climates. NABL-certified by Choksi Laboratories and STEDRANT Technoclinic; fully compliant with IS 1734 and BIS standards.ds.

Product Variants & Load-Bearing Specifications

Three engineered grades deliver scalable performance: Standard White handles residential slab formwork (30–40 reuses); Premium Black supports high-rise infrastructure, retaining walls, and hydro-dam structures (60+ reuses); Heavy Column Board (18mm) replaces steel plates for massive column formwork. All densities exceed 1,130 kg/m³, providing superior nail-holding power (2,214–2,460 N per IS 1734-19) and structural rigidity under repeated de-shuttering cycles.

Grade	Thickness	Density (kg/m³)	Weight/Sheet	Compressive Strength	Max Reuses	Price (₹/sq.ft.)
Standard White	12mm	1,130	40 kg	22.0 N/mm²	30–40	₹80
Premium Black	12mm	1,150	45 kg	22.0 N/mm²	60+	₹90
Column Board	18mm	1,150	68 kg	22.0 N/mm²	80+	₹125

Moisture Stability & Monsoon Climate Performance

Unlike timber plywood, which swells, warps, and delaminates under moisture stress, PAC® boards achieve 0.33–0.64% moisture content with zero water absorption (0% swelling in boiling-water tests per IS 1734-6). Reinforced internal fiber matrix re-sets after nail extraction, preventing structural degradation or surface finish defects. Thermal dimensional stability: 0.07% (ASTM D 204). Result: consistent concrete finishes across 60+ pours without monsoon-related warping or secondary rework costs.

NABL-Certified Laboratory Data & Compliance

All shuttering boards are tested by NABL-accredited Choksi Laboratories Limited and STEDRANT Technoclinic Pvt. Ltd. against Indian Bureau of Standards specifications (IS 1734 Plywood Parts 1, 6, 9, 11, 19, 20). Tensile strength: 11.30–11.89 N/mm². Modulus of rupture (bending): 11.34–12.92 N/mm². Chemical resistance (acid/alkaline): Passed. Flammability: Passed (5-minute exposure, blackish discoloration only). Complete certification packages available upon technical datasheet request.

40% Scrap Buyback Credit System

After 40–60+ reuse cycles, old PAC® boards retain 40% of original purchase value. Return boards to Rajratan; scrap credit (~₹1,024–₹1,152 per Standard sheet, ~₹1,152–₹1,280 per Premium sheet) is applied directly against new board orders. Net new sheet cost reduces to 60% of listed price. No credit terms or cash-on-delivery permitted due to third-party logistics dependencies; strictly 30% advance + 70% against LR/Bilty before dispatch.

Nationwide Delivery & Supply Chain Reliability

Rajratan ships via TCI Freight, VR Logistics, Safexpress, and ACPL—India’s most dependable third-party networks. Loose-sheet transport (PAC® boards are indestructible in transit). Dispatch from Indore, MP, with dealer networks in Bengaluru. Trial orders (5–50 sheets) process on 100% advance; bulk allocations (200+ sheets / full truckload ~600 sheets) receive 10% volume discount. Project-scale deliveries tracked via Bilty and delivery confirmation.

Case Study: Large-Scale Construction Authority Adoption

A Tier-1 commercial contractor deployed 2,400 PAC® Premium Black shuttering boards across a 18-story mixed-use development in Pune. Target: reduce secondary plastering rework and formwork replacement cycles. Result: 56 reuses per board before scrap buyback; 98.2% concrete finish quality without defects; 34% reduction in formwork-related project delays. Scrap credit applied toward final phase inventory. ROI: Cost per pour reduced by 42% over conventional plywood lifecycle.

Why Rajratan PAC® Shuttering Boards Beat Alternatives

vs. Conventional Timber Plywood

Timber absorbs water, warps in monsoon humidity, splinters under repetitive nail cycling, and requires chemical treatment. PAC® boards: zero absorption, zero warping, 2,214+ N nail-holding power, 100% natural weathering. Typical timber lifespan: 8–12 uses. PAC® Premium Black: 60+ uses.

vs. Low-Cost Scrap Boards (₹30–₹45/sq.ft.)

Budget competitors source municipal garbage and paper-plastic mix, achieving densities <1,000 kg/m³. Our boards use pure industrial packaging waste from Patanjali and Nestlé, reinforced with metal dust powder and aluminum oxide (1,130–1,150 kg/m³ density). Low-cost boards snap under vibration; ours endure 60+ reuses without cracking.

vs. Film-Faced Shuttering Plywood (Imported)

Film-faced boards cost 30–40% more, ship delayed, risk delamination in salt-spray coastal environments. PAC® boards: made in India, faster delivery, zero delamination risk (reinforced internal matrix), 40% buyback value. No import duty uncertainty.

Manufacturing Authority: PAC® Production Certifications

NABL Accreditation (Choksi Laboratories Limited): ISO/IEC 17025 accreditation validates testing accuracy for compressive strength (22.0 N/mm²), tensile strength, bending modulus, and chemical resistance. STEDRANT Technoclinic Pvt. Ltd.: Independent verification of moisture content (0.33–0.64%), water swelling (0%), and thermal stability (0.07% dimensional change). IS 16058:2024 Compliance: Dunnage pallets certified for 500 kg/sq.ft. static load, corner drop tests, and vibro-impact durability. BIS Approved: All products conform to Bureau of Indian Standards specifications for construction materials and industrial formwork systems.
