Joining composite decking joists

longwalks1

We are now planning to lay decking over our old patio as the quotes to replace it were coming in way too high. We will use composite joists, size 30mm x 50mm.  Composite as they’ll be laying directly onto the paving and also not to raise the level too high (30mm joist + 19mm/21mm deck boards)

the joists we've seen are 3m long, how are the joists joined together? (We were looking on Dino Decking) .  Unsure of how to cover a length requirement of 4m, and also how to join them at a 90 degree angle too?

Would the supplier not be the best people to ask about joints as they sell them and surely have been asked before.  I would suspect they would have some sort of bracket for straight and a different one for right angled connection.

Tried calling them but just an answerphone due to the Covid situation. Have sent an email and will take up to 72 hours for a response.  Was just wondering as planning what I need etc
