repairing charge taking place within the following
situations:
1) Accident due to careless handling and misusage;
2) Accident due to repair or improvement without permission of us;
3) Accident due to force majeure/nature disaster (fire, flood) and war.
Maintenance
we provide spare parts freely, including LED module, power supply,
fan, receiving card, LED lamps and other related parts. You can
replace the broken one with the spare parts when problem
happens, which will take about 5 minutes, and then send the broken
ones back to our factory for fixing freely before you don't have
enough spare parts for next maintenance. Additional
charges will be required if you want more spare parts. We offer
lifetime maintenance and charge only for the raw materials after
the guarantee period.

we offer training for free. Customer can send your engineer who has
electronic and computer knowledge to our factory for the
operation and maintenance training. We also provide the operation
manual, software, and so on. Any associated drawing of product and
structure and some other professional suggestion will be provided
too.
Installation
User's manual, instruction video, professional CAD installation drawing, and engineering drawings will be provided. We only offer the drawings, and you can show the drawing to your local steel structure factory, and they will weld it for you at site. On one hand, it's not cost-effective for you to ship the steel structure from China. On the other hand, we are impossible to offer you exact steel structure without welding at site.
Engineering training or installation assistance support at customer’s place is available, but a round-trip ticket, local accommodation of technician, staff labor cost (USD80/day if exceeding one week), cost of visa, and other expenses during the whole trip should be borne by the customer.
