1. PAINPOINT DRIVEN OPENING

Managing a quarry site in Lagos presents distinct operational hurdles that directly impact your bottom line. Are you contending with the high cost and logistical delays of importing prefabricated structural components? Are project timelines extended due to inconsistent supply or specifications that don’t match your exact site requirements? Fabrication work often faces bottlenecks from limited local capacity, leading to equipment downtime and missed project milestones. Furthermore, managing multiple vendors for design, material sourcing, and assembly introduces complexity and quality control risks.

What if you could source critical fabricated structures—from crusher support frames and conveyor galleries to plant buildings and maintenance platforms—at a predictable factory price, tailored for the demanding Lagos environment? This approach addresses the core challenges of cost control, timeline reliability, and specification accuracy for quarry infrastructure.

2. PRODUCT OVERVIEW: Custom Fabricated Structures for Quarry & Mineral Processing Plants

This service provides directfromfactory engineering, fabrication, and supply of heavyduty steel structures specifically for quarry and aggregate processing operations in Lagos and SouthWest Nigeria. We deliver custombuilt solutions designed to support your machinery and operational flow.

Operational Workflow:
1. Consultation & Design: Our engineers review your plant layout and load requirements to create detailed fabrication drawings.
2. Material Procurement & Preparation: Certified steel (Grade S355 or equivalent) is sourced, cut, drilled, and shaped using CNC machinery.
3. Assembly & Welding: Components are assembled by certified welders using procedures qualified for structural integrity.
4. Surface Treatment: All structures undergo abrasive blasting and application of highgrade industrial paint systems for corrosion protection.
5. Delivery & Installation Support: Finished fabrications are delivered to your Lagos quarry site, with optional provision of supervised installation teams.

Application Scope: Primary crusher bases, vibrating screen supports, conveyor system frameworks, feed hoppers, walkways, access platforms, maintenance gantries, equipment shelters, and modular plant buildings.

Limitations: Final onsite civil works (foundation pouring) remain the client's responsibility. Extremely specialized pressure vessels require separate certification.

3. CORE FEATURES

DesigntoSite Specification | Technical Basis: Clientdriven CAD modeling & finite element analysis (FEA) | Operational Benefit: Structures are engineered for your exact equipment loads and site footprint, eliminating adaptation delays | ROI Impact: Reduces installation time by an estimated 3040% versus adapting generic structures
LagosOptimized Corrosion Protection | Technical Basis: Multistage surface preparation (SA 2.5 blast cleaning) followed by epoxyprimer/polyurethane topcoat systems | Operational Benefit: Withstands coastal humidity and abrasive dust significantly longer than standard shop paint | ROI Impact: Extends maintenance repaint cycles from 18 to 36+ months, lowering lifetime upkeep costs
Modular Assembly Design | Technical Basis: Bolted connection designs with predrilled mating parts | Operational Benefit: Enables faster field assembly with less heavy lifting equipment required on your constrained site | ROI Impact: Cuts onsite labor hours by approximately 25%, reducing overall project risk
InHouse Material Verification | Technical Basis: Mill test certificate validation and ultrasonic testing of critical welds | Operational Benefit: Guarantees material grade and weld integrity before delivery to your location | ROI Impact: Prevents costly failures and unplanned downtime due to substandard fabrication
Integrated Service Points | Technical Basis: Prefitted lugs, cable trays, and pipe clamps as per your P&ID diagrams | Operational Benefit: Simplifies the installation of electrical, hydraulic, and water lines during plant commissioning | ROI Impact: Accelerates the path from installation to full operational status

Physical Dimensions: Fabricated in transportable modules; maximum standard module dimensions of 12m L x 3m W x 3m H for Lagos area road transport.
Environmental Operating Range: Designs account for ambient temperature range of 20°C to 45°C and wind loads as per Nigerian building code for industrial structures.

6. APPLICATION SCENARIOS

Granite Aggregate Plant Expansion Challenge:
Challenge: A major quarry near Ikorodu needed to install a new tertiary crushing circuit but faced prohibitive costs and lead times for imported support structures.
Solution: Full design and factory fabrication of a twolevel support platform for crushers and screens,
Results: Delivered within budget at a fixed price; installed in three days versus two weeks projected for piecemeal assembly; plant expansion commissioned six weeks ahead of schedule.

Conveyor System Overhaul Challenge:

Challenge: An existing conveyor gallery was failing due to corrosion fatigue,
Solution: Replacement with a customfabricated,
Results: New structure installed during a planned weekend shutdown with zero additional downtime; improved alignment reduced belt wear,
