type
  TStringArray = array of string;

function ConcatArrays( A1, A2: array of string): TStringArray;
var
  i: Integer;
begin
  SetLength( Result, High(A1) + High(A2) + 2 );
  for i := 0 to High(A1) do
    Result[i]:= A1[i];

  for i := 0 to High(A2) do
    Result[High(A1)+1+i]:= A2[i];
end;

using and testing:

procedure TForm1.Button1Click(Sender: TObject);
var
  StrArray1, StrArray2, ResArray: TStringArray;
begin
  SetLength( StrArray1, 3);
  StrArray1[0]:= 'Str 13';
  StrArray1[1]:= 'Str 12';
  StrArray1[2]:= 'Str 11';

  SetLength( StrArray2, 3);
  StrArray2[0]:= 'Str 23';
  StrArray2[1]:= 'Str 22';
  StrArray2[2]:= 'Str 21';

  ResArray:= ConcatArrays( StrArray1, StrArray2 );

  ShowMessage( ResArray[3] );
end;
