Formwork Material Transfer Iron Box - Efficiency Revolution in Construction Accessory Management

With "heavy-load durability + high-efficiency adaptability" as its core advantages, it adopts thickened Q235 steel and hot-dip galvanizing process, integrating stackable and foldable dual designs. It completely solves the industry pain points of traditional transfer tools, such as "insufficient load-bearing, high loss rate, and storage space waste". Having served more than 3,000 infrastructure projects worldwide, it reduces accessory loss rate from 15% to 2% and is certified as "preferred equipment for construction material management".

1.1 Heavy-Duty Structure, 5x Durability

The main body is made of 1.5mm thick Q235 cold-rolled steel plate, with the frame reinforced by ∠50×5 equal-angle steel. Formed by CO₂ gas shielded full welding with a weld leg height of ≥5mm, it can bear up to 800kg, far exceeding ordinary iron boxes (load-bearing ≤500kg). The bottom adopts a "well-shaped" double-channel steel structure with lateral support spacing ≤600mm, ensuring no deformation when lifted by forklifts; 5mm thick triangular reinforcing plates are added at the four corners, increasing impact resistance by 3x, suitable for frequent handling on construction sites. The surface undergoes hot-dip galvanizing (film thickness ≥80μm), passing 480-hour salt spray test without rust, remaining intact after 3 years of outdoor storage, and reusable for more than 50 times.

1.2 High-Efficiency Adaptive Design, 50% Space Saving

Standard size: 600×400×300mm (customizable from 500×300×250mm to 1200×800×600mm). The interior can be equipped with detachable partitions, suitable for classified storage of full-spec accessories such as Φ10-Φ50mm pins, connectors, and plugs, avoiding mixing loss. Innovative foldable side door design: closed for space-saving stacking, single-side opening for easy access without flipping the entire box; 200mm wide forklift pockets reserved at the bottom, compatible with manual pallet trucks, hydraulic forklifts and other handling equipment. Stable stacking up to 4 layers, increasing storage space utilization by 50%.

1.3 Humanized Details, Doubling Transfer Efficiency

Equipped with foldable steel tube handles (250mm extended length, fitting the box when folded) for labor-saving manual short-distance handling; clear size scales and load-bearing marks (MAX 800KG) on the side, enabling "at-a-glance" accessory counting and improving inventory efficiency by 60%. The top cover adopts bolt connection + butyl rubber gasket design, which is rainproof and dustproof. No moisture or rust of accessories during rainy outdoor transfer; rounded corners (R5mm radius) avoid personnel collision injuries, complying with construction site safety regulations.

1.4 Full-Cycle Cost Reduction, Cost-Effectiveness Leader

Compared with traditional wooden boxes (one-time use cost of 20 yuan), this iron box can be reused 50 times, with a single-use cost of only 1.2 yuan, reducing material packaging costs by 94%. The accessory loss rate drops from the industry average of 15% to 2%. For a 30-floor project, it can reduce pin loss by about 8,000 yuan; folded volume is reduced to 1/3 of the original, increasing single transportation capacity by 3x, cutting logistics costs from 1,200 yuan/vehicle to 400 yuan/vehicle, and reducing transfer costs by 67%.

3.1 Load-Bearing Core: "Well-Shaped" Reinforced Base

The base adopts double 8# channel steel lateral supports with a center spacing of 500mm, and additional reinforcing channel steel every 600mm longitudinally, forming a "well-shaped" load-bearing structure to disperse local pressure. Maximum deformation ≤1.5mm/m when lifted by forklifts. Full welding connection with the box (weld leg height 8mm), passing 200% rated load static test without cracking, suitable for 800kg accessory heavy-load transfer.

3.2 Adaptive Core: Multifunctional Handling Design

Symmetrically opened 200×150mm forklift pockets with rounded edges to avoid forklift tine impact damage; foldable handles on both sides (welded with φ20mm seamless steel tubes, covered with anti-slip rubber sleeves) bearing up to 50kg for manual handling, compatible with both mechanical and manual transfer scenarios.

3.3 Durability Core: Anti-Corrosion & Sealing Process

Dual anti-corrosion treatment of hot-dip galvanizing + passivation, with zinc layer adhesion reaching Grade 1 (no peeling in cross-cut test), resisting corrosion in humid and dusty construction environments; 5mm thick butyl rubber gasket between the top cover and the box, with waterproof washers for bolt connections. No leakage after 30-minute rain test (rainfall 5mm/min), ensuring accessories are not damp during long-distance transportation.
