The case weighs only 1.35KG. Thanks to its slim and lightweight design, it can easily fit into backpacks, electric vehicle storage boxes and briefcases for portable outdoor use.
The case is fully framed with bright thickened aerospace-grade aluminum-magnesium alloy profiles. The four corners are equipped with integrally stamped arc-shaped metal anti-collision corner protectors. Two metal anti-theft latches with brass key cylinders are fitted on the front, together with an embedded full-circle sealed rubber strip to deliver dustproof, splash-proof, drop-resistant and compression-resistant protection. Dual-side metal support brackets hold the lid open steadily. The base interior is lined with soft black flocking fabric, and various inner liners are available for optional matching. The ultra-thin flat inner cavity keeps small items neatly organized. It is suitable for on-site maintenance by plumbers and electricians, field equipment inspection, outdoor short-video shooting, safekeeping of financial seals and invoices, and carrying mini samples for exhibition displays. It effectively addresses common problems such as messy and easily lost small scattered tools, bumps and damages to precision mini instruments during transportation, and component corrosion caused by dust and moisture. It is a universal lightweight portable aluminum storage and protective case for maintenance workers, testing technicians, photographers and financial office staff.
Bright polished thickened aluminum-magnesium alloy frame with rounded metal corner guards: slim, drop-resistant and deformation-proof. The entire case is fully enclosed with high-brightness aerospace aluminum-magnesium alloy profiles. Four corners are fully covered with stamped rounded metal anti-collision corner caps that evenly disperse impact force during dropping, stacking and bumping, preventing the ultra-thin flat case from bending or denting. Two appearance options are available: matte black panel with silver aluminum frame, and full silver brushed panel. The surface resists cement dust, engine oil and fingerprints, and can be easily wiped clean with a damp cloth, making it suitable for both business and industrial scenarios.
Dual-key anti-theft metal latches with sealing design for dustproof and splashproof performance: Two symmetrical metal latches are fitted on the front of the case, with built-in brass lock cylinders and original matching keys. You can lock the case to store seals, expensive testing equipment and sets of precision tools. When the latches are fastened, they press tightly against the full-circle rubber sealing strip, effectively blocking construction site rainwater, dust and indoor moisture to prevent rust on internal metal tools and short circuits caused by dampness in precision instruments.
Dual-side metal support struts hold the lid open steadily to free your hand: Made of high-strength rust-proof metal, the support rods automatically lock the lid in place once opened. You do not need to hold the lid manually, leaving both hands free when inspecting equipment, sorting documents or arranging tools. The struts are firmly riveted and will not become loose or fall off even after tens of thousands of opening and closing cycles.
Ultra-thin flat lightweight body for easy portable storage: The case is only 90mm in height with an ultra-slim flat shape and weighs merely 1.35 kilograms. It fits easily into briefcases, backpacks and electric scooter rear compartments, taking up no extra space for on-site emergency repairs, field inspections and business trips, balancing solid protection and great portability.
Multiple liner configurations are optional to meet storage demands across various industries: The basic empty case comes with flocked soft interior for flexible storage of small and long items. Upgraded options include: ① Oxford cloth pockets on the lid for storing cables, documents and manuals; ② double-layer wavy shock-absorbing foam on the top and bottom, which can be freely cut to create slots for lenses and test probes. Custom one-piece molded EVA liners are available; exclusive independent slots can be milled according to the shape of your tools and instruments to keep items neatly positioned without shifting during transportation.
Weather-resistant composite panel with full-range customization services: The thickened frosted ABS composite panel paired with high-gloss aluminum-magnesium frame will not turn white, become brittle or crack under high and low temperatures, and resists water and electricity cleaners as well as mild acid and alkali corrosion. A flat blank area is reserved on the front for logo processing, supporting laser engraving and silk-screen printing of repair shop names, enterprise equipment serial numbers and corporate logos. For bulk orders, we can customize case colors, aluminum frame thickness and hardware latch styles.

Q1: What items can this ultra-thin aluminum case hold? What are the precautions for carrying and maintenance at construction sites and offices?
A: It is suitable for small tools for water and electricity maintenance, mini testing instruments, photographic accessories, as well as financial seals and documents. When carrying the fully loaded case, hold the bottom with both hands to prevent local heavy pressure on a single corner from slightly deforming the aluminum frame. After use at construction sites, promptly clear cement dust from the gaps of the aluminum frame.
Q2: Can the metal latches and supporting hinges be replaced individually if they are damaged?
A: The hardware parts are standard universal components. Contact customer service and provide the case model, and separate latches and hinges can be sent for self-replacement.
Q3: What is the waterproof performance of the case? Can the case be rinsed directly with water?
A: The case is only splash-proof and dust-proof for daily use. Do not submerge it in water for a long time or flush it directly with high-pressure water guns. For dirt, wipe the surface with a damp cloth and neutral detergent, and dry it thoroughly before storing equipment and documents.
Q4: How to confirm whether tools, instruments and seals can fit inside the case?
A: Measure the overall length, width and height of the items. If the measurements are smaller than the inner compartment size of 385×265×75mm, the items can fit completely. If the items are oversized, consult customer service for larger-sized aluminum protective cases.
Q5: Will the aluminum frame and metal handle get damaged easily when used outdoors on construction sites in cold winter weather?
A: Aluminum-magnesium alloy maintains stable toughness under low temperatures, so metal hardware is not prone to brittle cracking in cold conditions. Open and close the latches gently in low-temperature environments to reduce wear on the hardware.
Q6: What is the minimum order quantity for customized integrated EVA liners? Can separate slots be made for multiple small items in different zones?
A: The minimum order quantity for mold opening of liners is 300 pieces. Independent grooves can be made for multimeters, lenses and seals at the same time to store a full set of small items neatly in separate layers and zones.
Q7: How to clean and maintain the case when it gets stained with engine oil or ink paste?
A: Wipe the gaps of the aluminum frame and panels with a soft cloth and neutral detergent. Dry off water stains on metal hardware to prevent oxidation and rust. Do not store items until the case is completely dry, so as to avoid long-term residual stains corroding the aluminum-magnesium frame.
