Rode around this territory. Whole Latvijas Metāls is probably multiple territories. As I understand: 
On the west, separated by garages is a long thin strip of "Heidelberg Materials". 
Then Latvijas Metāls in borders: west - garages, east - Braslas and then wall under pipeline, north building 22K (excluding, not currently on map)
Probably rest is mentioned "Braslas industriālais parks" or it and a couple more separate entities (on the north)
22A, 22G and road near them are freely accessible, so not sure if the belong to park too.
