Packing Method:
a. bricks will be stacked on the export wooden pallets in order
b. there will be paper sheets between each layer of bricks
c. Orderly placed refractory bricks are wrapped around by plastic film to be waterproof
d. Eventually the four sides and top will be reinforced with plywood to prevent collisions
e. Pallet size no more than 1100x1100x1100 mm
