WP Query for WooCommerce

I created a special template a couple of years ago that uses wp_query to list blog posts. I am now trying to use this code for a website with WooCommerce products. I believe that WooCommerce products are a custom post type? So I should be able to slightly modify this script to do this? There is some special customization in here and that is why I am trying to use this method, but the stripped down basic part of the code is:

<?php 
		$my_query = new WP_Query('showposts=30'); 
 while ($my_query->have_posts()) : $my_query->the_post();?>
<strong><a href='<?php the_permalink() ?>'><?php the_title('', '...', true, '35') ?></a></strong>
<a href='<?php the_permalink() ?>'><?php echo get_the_post_thumbnail($page->ID, 'thumbnail'); ?></a>
<?php the_excerpt(); endwhile; ?>
