Export Guide: Electrolytic Plate Sandwich Panel Salt‑spray Selection

Step 1 ❓Sort out target‑export‑region environment and project conditions First confirm project location, distinguish coastal or inland. Collect climate factors: humidity, salt‑mist level, UV intensity and sand‑dust condition. Meanwhile confirm industry type (electronics, pharmaceutical, food, laboratory), clean‑room classification and local building codes. ‑ Southeast‑Asia coastal: high temperature & high humidity plus chloride salt‑mist corrosion; island areas deliver the strongest corrosion. ‑ Middle‑east: high temperature and strong UV. Inland areas suffer sand‑dust abrasion; partial coastal cities have salt mist. ‑ Europe: mild dry inland climate; coastal areas such as Mediterranean and North Sea are exposed to ocean salt mist. SAMZOON provides electrolytic plate sandwich panel selection suggestions and free samples according to regional working conditions.

Step 2 🌏Match basic salt‑spray index of electrolytic plate sandwich panel for corresponding regions Select NSS neutral salt‑spray baseline according to target regions:

1. Southeast Asia ‑ Inland cities of Southeast Asia: 48h NSS ‑ Southeast‑Asia coastal: 72h NSS ‑ Southeast‑Asia islands: 96h NSS
2. Middle East ‑ Middle‑east inland sand‑storm zones: 48‑72h NSS, improve coating UV‑resistance and paint hardness against sand abrasion ‑ Middle‑east coastal cities: 96h NSS, balance salt‑spray resistance and UV performance
3. Europe ‑ European inland: 48‑72h NSS, coating must meet low‑emission clean‑room requirements ‑ European coastal (Mediterranean, North Sea): 96‑120h NSS, follow ISO 9227 standard

Note: Electrolytic plate owns thin zinc layer. Anti‑corrosion performance mainly relies on sprayed coating. Salt‑spray rating represents coating property instead of bare substrate anti‑corrosion capacity.

Step3 🧪Verify full coating technical parameters for electrolytic plate sandwich panel Do not only focus on salt‑spray hours, check full‑set indicators:

1. Paint‑film thickness on both front and back sides; single‑side painting is forbidden.
2. Salt‑spray test standard: ISO 9227 or ASTM B117.
3. Salt‑spray acceptance criteria: no red‑rust, no blistering grade.
4. Paint‑film adhesion and surface hardness.
5. Clean‑room performance: low‑emission and low‑VOC for clean‑room application. SAMZOON supports custom‑built electrolytic plate sandwich panels. Coating parameters can be adjusted for export orders, salt‑spray test samples are available.

Step4 📜Check local compliance and customer technical document requirements Most European clients require ISO 9227 test reports. Some overseas buyers demand third‑party inspection reports. Make certain the test sample is finished electrolytic plate sandwich panel face sheet rather than bare metal substrate. Record salt‑spray standard, duration and acceptance criteria for PI technical appendix preparation.

Step5 ✅Integrated panel matching: face sheet plus core‑material combination Matching core‑material options for electrolytic plate face sheet: ‑ Electronic clean‑room projects: electrolytic plate + PU / PIR sandwich panel ‑ Fire‑resistant projects: electrolytic plate + magnesium‑glass sandwich panel Core material shall comply with local fire‑resistance and thermal‑insulation regulations of target market. Do not only focus on face‑sheet salt‑spray performance.

Step6 🚢Lock complete written specifications for export order Write all parameters clearly within PI and technical appendix: electrolytic plate substrate thickness, electro‑galvanized zinc weight, front‑and‑back paint‑film thickness, salt‑spray test standard, salt‑spray duration, acceptance criteria, core‑material specs and packaging standard. Verbal agreement shall be avoided to prevent production parameter deviation.

Step7 🚢Ocean‑shipping packaging protection configuration Even with high salt‑spray grade, container condensation may still damage electrolytic plate coating:

1. Fully wrap panels with waterproof stretch film, adopt plywood pallets.
2. Place sufficient desiccants inside containers.
3. Control stacking height to avoid compression scratches on panel surface. Once coating gets damaged, sea salt mist will quickly generate rust spots.

Step8 ✅On‑site acceptance and storage management after goods arrival Conduct random inspection after container opening: check electrolytic‑plate surface for scratches, paint chipping and shipping‑caused rust, compare against reference sample. Store panels indoors under dry and ventilated environment. Outdoor stacking is strictly forbidden. Lift panels off ground and keep away from damp walls. Use soft protective tools during handling to protect coating.

Step9 ✅Construction and later‑stage maintenance tips Take protective measures during cutting and welding work to prevent high‑temperature burning on electrolytic‑plate coating. Timely apply touch‑up paint for minor coating damage to stop rust spreading.

Overseas Project Summary ⚠️

1. Do not apply one set of salt‑spray parameters to all export regions, corrosion mechanisms vary from place to place.
2. Salt‑spray rating is laboratory performance. Sea‑shipping packaging, loading‑unloading and storage also decide real‑world service life of electrolytic plate sandwich panels.
3. Pre‑shipment sample testing is highly recommended for export orders to reduce overseas after‑sales risks.
