Product Certification
Product packaging 
1. Principles of Packaging Design
Protection Shock proof and buffering: precision accessories (such as instruments and valves) need to be filled with foam, bubble film, pearl cotton, etc. to avoid damage caused by transportation shock.
Moisture and rust prevention: Metal components (such as pipelines and flanges) need to be coated with rust prevention oil and packaged with moisture-proof film or vacuum. Desiccant should be added during sea transportation.
Anti pressure and anti drop: Heavy accessories (such as burners and drums) are reinforced with wooden boxes or steel frames, indicating the load-bearing direction and stacking layer limits.

2. Standardization and identification
Comply with international transportation standards (such as ISO, ISTA), indicate weight, size, lifting point, "fragile", "moisture-proof", "upward" and other markings.
Dangerous accessories (such as fuel injectors) must be labeled with UN certification and comply with the International Maritime Dangerous Goods Code (IMDG).

3. Container division strategy
Small items (bolts, washers) should be packaged in a uniform size box to avoid loose parts; Large items (heat exchangers) are individually customized in wooden boxes with supporting frames inside.

Product transportation
Transportation mode selection
1. Shipping by sea
Suitable for bulk accessories such as steel plates and large pipelines, pay attention to container size (20GP/40HQ) and load balance.Sea freight requires anti salt spray treatment, with moisture-proof agents placed inside the container and sealed.

2. Land transportation
Heavy accessories (over 3 tons) require flatbed trucks or low chassis vehicles, and routes should be planned in advance to avoid height/weight restrictions.Cross border transportation inspection of various countries' requirements for wooden packaging (such as ISPM15 fumigation certificate).

3. Air freight
Urgent small items (electronic controllers) should be prioritized for air transportation, and the weight of each item should be controlled (usually<100kg) to reduce packaging weight and save costs.

FAQ:
Frequently Asked Questions on Cold rolled Steel coil Sales (Q&A)
Q1: Can the hardness of cold - rolled steel coils be adjusted?
A1: Yes. It can be adjusted as needed through heat treatment processes such as annealing (to reduce hardness and improve plasticity) and
quenching + tempering (to enhance hardness while optimizing toughness).
Q2: Is the low - temperature performance of cold - rolled steel coils affected?
A2: Ordinary carbon cold - rolled coils are prone to cold brittleness at low temperatures (toughness decreases and brittleness increases); cold - rolled
coils containing alloys such as nickel/manganese have better low - temperature toughness and can be adapted to severe cold environments.
Q3: Can cold - rolled steel coils with special specifications be customized?
A3: Supported. Thickness (such as ultra - thin 0.15mm, thick 3.5mm), width (non - standard 500mm narrow width, etc.), and surface treatment
(galvanizing/color coating, etc.) can be customized. It is necessary to
communicate the minimum order quantity and delivery time in advance.
Q4: What tests are required to detect the performance of cold - rolled steel coils?
A4: Tensile tests (to measure strength/plasticity), bending tests (to verify formability), and hardness tests are mandatory; for special requirements
(such as corrosion resistance), additional tests such as salt spray tests and intergranular corrosion tests are carried out.
Q5: How to store cold - rolled steel coils?
A5: Store in a dry and well - ventilated warehouse, away from acid - base/humid environments; place wooden blocks between coils to avoid crushing;
if stored exposed, cover with waterproof cloth to prevent rusting.
