As the digital logistics corridors and manufacturing zones expand across the Philippines, the demand for flexible, modular warehouse storage has reached unprecedented heights. Foshan Dinghui Intelligent Warehousing Technology Co., Ltd. engineered our signature Butterfly Hole Storage Shelving to provide ultimate structural strength, instant boltless adjustment, and lifetime durability. Discover our top-tier designs optimized for regional logistics channels.
The industrial landscape of the Philippines is undergoing a historic decentralization. As urban centers like Metro Manila experience high real estate costs and density challenges, the Luzon Economic Corridor, encompassing key investment zones in Pampanga, Bulacan, Clark, and Subic, is driving logistics real estate to a record high. Additionally, CALABARZON (Cavite, Laguna, Batangas, Rizal, and Quezon) remains a stronghold for advanced manufacturing and electronics assembly, operating under the structural guidelines of the Philippine Economic Zone Authority (PEZA).
In this dynamic landscape, warehouses and distribution centers require shelving units that provide fast installation, spatial flexibility, and robust loading limits. The butterfly hole shelving system (also widely known as light-to-medium-duty boltless racking) has emerged as the system of choice for modern retail warehousing, e-commerce micro-fulfillment centers, agricultural supply repositories, and cold storage applications. By eliminating bolts, nuts, and complex cross-bracing structures, facilities can rapidly construct storage configurations, saving thousands of labor hours during system rollouts.
At the heart of the butterfly hole shelf is its interlocking mechanism. Unlike traditional slot patterns or keyholes, the butterfly cutout is engineered with a taper that mirrors the profile of a butterfly's wing. The beam connector rivet drops into the wide top portion of the slot and wedges down securely into the narrow bottom throat.
As load is applied to the horizontal beams of the shelf, the downward pressure pushes the structural rivets tighter into the butterfly taper. This creates a self-bracing connection that resists lateral forces, maintaining perpendicular alignment under maximum capacities.
The Philippines rests along the Pacific Ring of Fire, subject to consistent seismic activity. Boltless connections possess natural ductility compared to rigid welded systems, distributing kinetic energy evenly during minor seismic shifts to prevent brittle failures.
Manufactured from high-grade Q235B cold-rolled steel, the uprights and beams achieve high yield strength with minimized weight, preventing premature bowing under static loads and assuring warehouse workers of optimal occupational safety.
For structural stability, our upright columns undergo multi-stage roll forming. Precision CNC punches shape the butterfly holes at pitch intervals of 50mm or 75mm, allowing users to modify shelf heights by hand without using heavy-duty tools. This modular adaptation is crucial for logistics centers that deal with seasonal cargo transitions.
One of the most persistent operational threats facing storage equipment in the Philippines is the high relative humidity (averaging 70%-80% annually) and the presence of coastal salinity in major ports like Manila, Batangas, and Cebu. Exposure to these factors can cause rapid oxidization of raw steel, resulting in structural failures.
Foshan Dinghui implements a comprehensive surface protection treatment that outperforms standard manufacturing practices:
Whether you are setting up a large third-party logistics (3PL) warehouse in Laguna or a local distributor warehouse in Cebu, our team of 18 senior R&D engineers will help you customize load capacities, layout configurations, and powder coatings.

Foshan Dinghui operates a massive 38,000 square meter manufacturing base in Guangdong, China—the global epicenter of industrial steel production. This proximity to premium raw material suppliers allows us to hedge steel prices effectively and guarantee a constant supply of high-grade raw components, even during periods of global market volatility.
Our logistics efficiency is optimized for the Southeast Asian shipping corridors. By loading directly from the ports of Guangzhou, Shenzhen, or Foshan, we ensure direct sea freight transit to Manila North Harbor, South Harbor, and Cebu Port in just 7 to 12 days. Our professional trade operations team handles customs clearing paperwork, export tax exemptions, and certificate of origin (Form E) documentation to help Philippine buyers minimize import tariffs under the ASEAN-China Free Trade Area agreements.
At Foshan Dinghui, quality assurance is integrated into every step of our manufacturing. We maintain a 35-member internal QA/QC team that tests every single production batch. The raw steel undergoes tensile testing before loading into roll forming machines. Finished beam structures are subjected to hydraulic stress simulations to confirm their exact deflection parameters under maximum static loads.
We implement non-destructive inspection (NDI) on all welding seams to ensure structural continuity. All storage racks produced in our facility strictly conform to ISO 9001:2015 quality systems and carry the European CE certificate. These certifications provide our Philippine partners with the documentation needed for local safety audits, industrial building permits, and international insurance policy underwriting.

Modern storage is moving beyond passive load-bearing structures towards intelligent, dynamic systems. As regional logistics in Manila, Clark, and Davao transition to automated systems, traditional racking must adapt. Our engineering team has drafted a strategic roadmap to integrate conventional butterfly shelving into automated, modern environments:
Adapting the base profiles and stability ratios of our butterfly racks to allow seamless integration with Automated Guided Vehicles (AGVs) and robotic picking systems.
Integrating RFID tags and IoT load sensors directly into the cold-rolled beams to provide inventory managers with real-time weight tracking data.
Developing next-generation organic, zero-VOC powder coatings that meet international environmental certifications without sacrificing corrosion protection.
By investing in our flexible boltless systems today, businesses secure a modular foundation that can easily scale, move, and integrate with future automated technologies.

Our butterfly hole shelves are designed for light-to-medium-duty storage. Depending on the steel thickness (0.6mm to 1.2mm for panels; 1.0mm to 2.0mm for uprights), the loading capacity ranges from 150 kg to 500 kg per shelf layer under evenly distributed static loads. We can customize the thickness parameters based on your target weight requirements.
Our products undergo an advanced multi-step pretreatment process including acid pickling, surface conditioning, and phosphating. We then apply an electrostatic epoxy-polyester powder coating (60-80 microns thick) cured at 180°C to 200°C. This creates a dense, non-porous barrier that prevents moisture and salt ions from contacting the steel substrate.
No, the key advantage of the butterfly hole design is its boltless structure. The beams hook into the uprights manually, requiring only a simple rubber mallet to secure the joints. A typical 4-tier rack can be fully assembled by two workers in less than 10 minutes, drastically cutting down installation costs compared to traditional bolted racks.
Our factory in Foshan, Guangdong is close to major international shipping ports like Nansha (Guangzhou) and Shekou (Shenzhen). Sea freight transit time to Manila North/South Harbor is 7 to 10 days, and to Cebu or Davao is 10 to 14 days. Production lead times average 15 to 20 days depending on the volume of order customization.
Yes, we provide a complete set of export documentation, including the ASEAN-China Free Trade Area Preferential Tariff Certificate of Origin (Form E). This certificate allows Philippine importers to claim zero or significantly reduced import duty rates, lowering total procurement costs.
